Facts About Geotech Engineering And Testing You Need To Know

By Christine Meyer


In engineering, there are many branches. One of them is the geotechnical study which mainly deals with the analyzing how Earth materials behave; mostly known as soil. Studying the earth material is usually under civil engineering, and therefore it connects geotech engineering and testing in it.

In the past, there were no prior testing nor evaluation on the soil before the necessary activities were carried out. The practice gained most fame during the eighteenth century. Today, all soil related activities example, construction, military, and mining are done after a research of the soil in the area has been carried out. The research helps in determining whether carrying out the activity in the area is recommended.

As a discipline, it is concerned with analyzing soil quality. The soil is made up of many elements such as rocks or minerals, air, and water. Their nature keeps changing over time owing to natural and human forces and occurrences. Therefore the properties as they appear at the time of the study were not so a few years ago. On the same note, they would also change over the coming years. Going by this fact, soil properties should be investigated to determine the suitability of the intended use at the actual time of need. It is not an activity whose old results can be used in the present.

By scientifically investigating the surface materials, geotechnical experts can determine the chemical and non-chemical properties of the soil beneath. They are also able to evaluate the stability of the soil as influenced by both natural and human activities. They also conduct a risk assessment as would be caused by construction site preparations, earthworks as well as mining and water drilling. They can determine the suitability of a surface for any earthworks that would interfere with the nature the surface.

The process of determining the engineering properties of the soil are done in steps. The steps will first begin by what you know and then progress to the unknown factors. The activity is thus handled as if it is a project. While following the steps, guidelines regarding the qualities are used to confirm that the soil is suitable for construction.

The project is usually broken down into other smaller projects and carried out one at a time before the conclusion is reached. The first step is usually to visit the site and get the whole view of the area as it has been influenced by its surroundings. The main aim is usually to check the risk to humans that can be brought about by the human forces or natural forces so that they make the correct recommendation of the site.

When the geotechnical procedure is carried out correctly, it will be easy to reduce some natural disasters like the earthquakes and mass wasting. When the geotechnical engineer has determined the soil properties, they will be able to prescribe the suitable foundations for the site. The results from the soil survey can also help determine the changes of the initial construction designs.

As a discipline, geotechnical study is wide. It also interrelates with other disciplines such as history and geology. This is because humans use soil for many purposes, and the use affects the properties it has at any given time.
