topografia y estudio de mecanica de suelos

While topography and soil mechanics are different disciplines, they complement each other to benefit construction projects. An accurate topographic survey is essential to achieving an optimal soil study. The calculations provided by topography serve as an important foundation and critical complement to geotechnical analyses.

Let’s explore how topography helps develop a proper soil study:

Understanding the Terrain’s Relief

Topographic studies help us understand the following key aspects in soil mechanics studies:

  • Identification of slopes, depressions, and elevations in the terrain. This knowledge is crucial to determining how these features affect the distribution of loads on the soil.
  • Precise location of areas for soil mechanics tests. Topographic information aids in pinpointing the best spots to conduct these tests accurately.

Identifying Areas with Stability Issues

Based on topographic information, soil mechanics can help identify:

  • Areas within the terrain that may present stability issues or are prone to landslides.
  • Optimal zones for conducting boreholes or trial pits based on specific characteristics of the terrain.

Additional Benefits of Topography for Soil Mechanics Studies

  • Creation of three-dimensional models that integrate terrain morphology with geotechnical information to simulate soil behavior under loads or excavations.
  • Provides insights into surface water behavior, helping analyze phenomena like erosion, seepage, and soil saturation, which can affect its mechanical properties.
  • Assists in identifying the most suitable areas for construction, avoiding zones with geotechnical instability or those requiring additional structural reinforcement.
  • Ensures the necessary knowledge for machinery to access testing sites safely and efficiently.

Each project is unique, and so is each terrain. It is crucial for engineers and architects managing construction projects to plan the necessary geotechnical studies properly.

What Errors Occur in Topography and How to Avoid Them?

conoce los errores en la topografia

Topography, like any discipline, demands expertise and knowledge to avoid errors and achieve optimal results. In our field, accuracy is critical, as even minor errors can accumulate and lead to significant negative consequences in engineering projects if not detected in time.

The main types of errors in topography are systematic errors and accidental errors. Let’s understand how they arise and how to prevent them to ensure the quality of the results.

Systematic Errors

These are deviations that occur due to equipment malfunctions, incorrect calibrations, improper procedures, or environmental factors. Systematic errors tend to repeat under the same conditions and, if not corrected, can lead to consistently inaccurate results.

Examples of systematic errors:

  • Uncalibrated total stations, damaged leveling instruments, etc.
  • Environmental factors such as light, metal expansion due to heat, or fog affecting instrument readings.

Accidental Errors

These are deviations caused by unpredictable variables such as human error or accidental instrument movements. While they are unavoidable to some extent, these errors are typically minor when proper procedures are followed.

Examples of accidental errors in topography:

  • Instrument reading errors due to operator distraction or carelessness.
  • Vibrations in the terrain caused by machinery or other external factors.

How Do We Prevent These Errors?

As a specialized topography company, we implement procedures to minimize errors and ensure the reliability of our work. Below are the measures we take:

To Prevent Systematic Errors:

  • Regular maintenance of equipment: We have preventive maintenance plans to ensure all instruments function perfectly.
  • Calibration and verification: Total stations and levels are calibrated and checked before any project.
  • Evaluation of atmospheric corrections: Adjustments are made for environmental factors, such as material expansion on hot days.
  • Deviation tests: These tests are conducted to identify potential systematic errors.

To Prevent Accidental Errors:

  • Continuous training: We provide regular training and updates to our personnel.
  • Advanced technology: Our tools feature integrated viewers and systems to reduce common errors.
  • Comparative measurements: We conduct multiple measurements to identify and eliminate inconsistencies.

The Gauss Curve and Its Application in Topography

The distribution curve, or Gauss curve, helps identify potential errors by analyzing deviations in the data. It allows us to distinguish between systematic and accidental errors effectively.

This statistical tool enables informed decisions about the quality of the collected data and the implementation of corrections when necessary.

Setting Out in Topography: Key to Error-Free Construction

ingeniero topografo

Once a topographic survey has been conducted, companies gain precise information about the land where construction will take place. A topographic setting-out is the process of validating the data from the prior survey to initiate the construction process.

Why is setting-out important?

A setting-out ensures that the structure is correctly positioned, avoiding errors that could lead to additional costs and project delays. While there are usually ways to validate information from a topographic survey, setting-out minimizes the risk of any erroneous values persisting.

How do we carry out our setting-out process?

  1. Preparation: We analyze the technical design and determine the key points to be marked on the site.
  2. Positioning: Reference points are established using tools like total stations, optical levels, or GPS.
  3. Marking: Stakes, lines, and other marks are placed to serve as guides for construction teams.

Applications

  • Construction of buildings, roads, and bridges.
  • Industrial facilities and plants.
  • Urban development projects and public utility networks.

Is it advisable to conduct topographic surveys during construction?

torre de pisa inclinada por falta de estudios topograficos

Regarding topography, it is often believed that this study is only necessary at the beginning of construction work; however, this view does not fully reflect the true purpose of a topographic survey.

It is essential to consider that these studies, in addition to providing a precise view of the terrain’s characteristics, can help us identify changes in the alignment of structures as they settle, ensuring the correct placement of structures and helping to prevent issues that may arise from discrepancies in elevation, alignment, and terrain configuration. Without this detailed information, construction can face significant risks that impact both the safety and functionality of the structure.

importancia de la topografia continua
Key reasons to conduct topographic surveys during construction:

  1. Precision control and alignment: Surveys help verify that all elements of the construction are correctly aligned, preventing deviations in walls, columns, and foundations.
  2. Minimizing structural risks: Detecting anomalies in the terrain, such as sinking or landslides, allows for preventive actions and plan adjustments to ensure structural stability.
  3. Efficiency in material usage: Knowing the precise terrain profile enables optimization of the required material quantities, reducing waste and additional costs.
  4. Mitigating legal issues and conflicts: Accurate surveys ensure that construction is carried out in the correct location and within property boundaries, avoiding property disputes and legal issues.

Historical Case: The Leaning Tower of Pisa

A famous example of the consequences of inadequate planning and lack of detailed topographic and geotechnical studies is the Leaning Tower of Pisa in Italy. Construction of this tower began in 1173, and due to the lack of thorough terrain studies, the tower’s foundations were insufficient to support its weight on soft, uneven ground. This caused the tower to begin leaning during its construction, creating a significant risk of collapse.

With today’s advances in topography, the leaning and structural problems of the Tower of Pisa would have been detected much earlier, allowing for design or foundational adjustments to prevent the tilt. Today, this tower remains an example of the importance of conducting topographic and geotechnical studies, not only at the beginning but at every stage of a construction project, to ensure the stability and safety of buildings.

Types of Objectives in Topographic Surveys

Topographic studies, also known as topographic surveys, are a fundamental tool in engineering, construction, architecture, and urban planning due to the valuable information they provide about the terrain.

There are various types of topographic surveys, each with specific objectives adapted to the needs of your project. Below, we describe the main types of topographic studies, each with its respective objectives.

  1. Geodetic Surveys

Geodetic surveys are essential for precise topographic mapping. Their objective is to create a framework of reference points with exact coordinates through the use of global navigation satellite systems (GNSS).

These surveys are crucial for large-scale projects, such as road and highway infrastructure, coastal city construction, and more. They provide reliable data to locate structures and other elements in relation to a global coordinate system.

  1. Plane Surveys

A plane survey allows for detailed measurements within specific areas. It is widely used for limited areas and coordinate delineation projects as it does not account for the Earth’s curvature. Traditional tools like theodolites and levels are used to measure distances, angles, and elevations, ensuring precision in local projects.

  1. Airborne Surveys

With the help of unmanned aerial vehicles, such as drones, airborne surveys have become more efficient. These include drone photogrammetry and LiDAR (Light Detection and Ranging), with the goal of capturing extensive data over large areas quickly and accurately.

These aerial topographic studies enable the creation of three-dimensional terrain models, useful for urban planning, environmental monitoring, and evaluating inaccessible areas.

  1. Construction Surveys

Specifically designed for the construction industry, construction surveys aim to provide precise data for buildings. It is recommended to conduct them from site preparation through to the final verification of structures.

This type of topographic study ensures that buildings, roads, and other infrastructure are constructed according to design specifications and meet regulatory standards, preventing costly errors in project execution.

  1. Boundary Surveys

Boundary surveys aim to define and delineate property lines and are essential for resolving land disputes, property transfers, and compliance with zoning regulations.

  1. Hydrographic Surveys

The objective of hydrographic surveys is to map underwater features, such as depths, shoals, and obstacles. These studies are essential for navigation, marine construction, and coastal zone management. Thanks to this type of study, a detailed profile of the waterbed can be obtained for projects such as port dredging and maintenance of navigation routes.

Differences and Similarities Between Topography and Geodesy

topography survey company

Topography and geodesy are sister disciplines that provide us with advanced knowledge of the surfaces in a given area.

Topography studies relatively small surfaces where precision is required for the construction of industrial plants, factories, houses, hydroelectric plants, etc. Geodesy, on the other hand, carries out these studies over much larger areas, such as the extension of a highway spanning hundreds of kilometers, the laying of a railway line connecting several cities, international airports, electrical grid systems, and more.

As we can see, the purpose of both studies is quite similar, but the scales are fundamentally different. For this reason, each uses distinct techniques and instruments.

Below is a list of the main differences between geodesy and topography:

Aspect Topography Geodesy
Scope and Scale Focuses on small, local areas like construction sites. Covers large areas, including continents and the entire planet.
Earth’s Curvature Not considered in small projects. Considers Earth’s curvature over long distances.
Instruments Total stations, optical levels, drones. GPS, GNSS systems, satellites.
Method Measures distances, angles, and elevations in local areas. Establishes global coordinates and studies Earth’s shape.
Applications Construction projects, land surveying, urban planning. Tectonic studies, global positioning systems (GPS).
Time Scale Used for short-term, specific projects. Used for long-term studies, including geological changes.
Coordinate Systems Uses local coordinate systems for precise locations. Uses global coordinate systems (e.g., WGS84).
Precision High precision in small areas. Precision adjusted for large-scale and global phenomena.
