Geotechnical bodies are products of nature, the formation process, material composition and engineering characteristics of which are extremely complex and become more complex with differences in stress state, stress history, loading rate and drainage conditions, etc. Therefore, before various engineering project designs and constructions are carried out, geotechnical tests and in-situ tests must be carried out on geotechnical bodies on sites where engineering projects are located, so that the physical and mechanical properties of the geotechnical bodies can be fully known and mastered, and necessary basis is provided for correct evaluation of site geotechnical engineering conditions. The geotechnical test is the early work of geotechnical engineering planning and design and is also an indispensable central link in foundation and foundation design work. All engineering construction projects, including buildings, underground engineering, highways, railways, tunnels and the like, have close relation with geotechnical bodies on which the engineering construction projects depend, to a great extent, depend on whether the geotechnical bodies can provide enough bearing capacity, depend on whether the engineering structures are not subjected to more than allowed foundation settlement, differential deformation and the like, and parameters in calculation of the bearing capacity and the deformation of the foundation are mainly determined by geotechnical tests, so the geotechnical tests are indispensable for construction of various engineering projects.
