Geotechnical engineers mainly study the engineering characteristics of geotechnical components. Firstly, it studies the geotechnical samples collected from the construction site and the data in the geotechnical samples, and then calculates the grid needed by the buildings in the construction site. Design of foundations, piles, retaining walls, dams, tunnels, etc. Need the advice of geotechnical engineers.

The development of geotechnical engineers can be divided into two parts: one is in consulting companies, which are the main service enterprises for geotechnical engineers in the future. Mainly responsible for survey, testing, design, inspection, monitoring and other work related to data, demonstration and decision-making. The other is in an engineering company, mainly responsible for the implementation of geotechnical engineering.

Note: Numerical geomechanics is an effective means to solve geotechnical engineering problems, which has been widely accepted by academic and engineering circles. As a tool for analyzing mechanical state, it is increasingly applied to stability analysis of rock and soil, geotechnical engineering design and analysis of basic geotechnical engineering problems.

With the continuous expansion and extension of geotechnical engineering, numerical analysis methods of geotechnical mechanics have developed rapidly, and various numerical analysis methods have appeared. The commonly used numerical analysis methods of geotechnical mechanics are divided into continuous deformation analysis method and discontinuous deformation analysis method.
