What Is Geotechnical Survey? How To?

Geotechnical survey is a research process to determine the physical and mechanical properties of the ground before construction projects. This study aims to evaluate the bearing capacity of the ground, ground water level, compressibility of the ground and other important parameters in order to ensure that the structures to be built are safe and durable. In this article, we will explain what a geotechnical survey is and how to do it.

The Importance of Geotechnical Survey

Geotechnical survey is of great importance for the successful realization of construction projects. The bearing capacity of the soil, groundwater level and other soil characteristics are critical factors that must be taken into account in the foundation design of structures. If a building is built without a geotechnical survey, problems may occur such as the ground having less bearing capacity than expected or the ground water level being high. This may damage the structure or pose a safety risk.

How to Perform a Geotechnical Survey?

Geotechnical survey is usually carried out by an engineering firm or an expert team. Here are the basic steps:

Step 1: Project Evaluation In the first step, the project and requirements of the building to be built are evaluated. At this stage, information about the structure, design specifications and other relevant documents are examined.

Step 2: Land Survey The field is visited and various tests are performed to determine the physical properties of the ground. These tests include drilling, sampling, ground compression tests and measuring the ground water level.

Step 3: Laboratory Tests The sampled soil samples are sent to the laboratory and subjected to various tests. These tests are aimed at determining the bearing capacity, compressibility, permeability and other mechanical properties of the soil.

Step 4: Data Analysis and Reporting The obtained data is analyzed and a geotechnical survey report is prepared. This report includes the bearing capacity of the ground, ground water level, thickness of soil layers and other important parameters. The report provides structural engineers and designers with information about the properties of the ground and ensures that the structure design is made according to this data.

As a result, geotechnical survey is an important step in construction projects. Done correctly, it ensures that the structures are safe and durable. This survey includes various tests and analyzes to determine the physical and mechanical properties of the soil. This process provides structural engineers and designers with important data about the ground and ensures that the structure design is made according to this data.
