What is meant by Geotechnical Engineering and what does they do?

Geotechnical engineering

 

Geo technical engineering is a branch on civil engineering that deals with soil and rock behaviour. This also involves to assess the slope stability and the risk of landslides, rock falls and avalanches. The word geotechnical refers to the geological components of the earth like the earth, soil and also the groundwater. They also assess the risks posed by the site conditions. Geo technical engineering is also applicable in Military, mining and petroleum along with other engineering disciplines like construction that is done on the surface or within the ground.

 

What does they do?

 

 

Geotechnical engineering helps in determining the physical, mechanical and chemical properties of soil and rocks. A geotechnical engineer skills are used for drilling wells, transporting petroleum products, construction of production and storage facilities and also examining ground water flow. Geotechnical engineers plays a crucial role in all civil engineering projects, Before commencing any construction work it is very important to do a site investigation.  Because if the investigation is not carried out properly it can be very expensive and can carry negative consequences also.

Geotechnical engineers guard and maintain the earth's physical environment during the development of major projects. They also combine there expertise in civil engineering, construction and design which enables them to safely investigate and analyse the project sites and determine  their present and future stability. Geotechnical engineers provide analysis and mapping of technical results obtained from seismic surveys and investigate subsurface conditions and materials to determine their properties and risks. They also design pitwalls, mine waste dumps & dam structures used in oil sands mining and analyses the slope stability .
