Geotechnical engineering research objects are complex geological bodies, in the long geological age, due to the movement of geological structures, natural weathering and human activities, a large number of geological defects such as faults, stratigraphy, joints, weak interlayers, lyssol ditches, troughs and so on have been formed. Under certain time and conditions, the rock and soil may be in a relatively stable equilibrium state; If the conditions change, the original equilibrium state may be destroyed, such as in the process of geotechnical excavation and construction, its original stress field is redistributed, resulting in deformation of the rock and soil, resulting in geological disasters such as collapse, collapse, rock avalanche, landslide and ground settlement.

In order to prevent and control such disasters, the project often buries a strained member into the rock and soil body to mobilize and improve the self-strength and self-stability of the rock and soil body, which is called the anchor rod or anchor cable (hereinafter collectively referred to as the anchor rod), and its role is anchoring. Techniques and processes that use scientific knowledge such as mathematics, mechanics and engineering materials to solve problems in anchor design, calculation, construction and monitoring in geotechnical engineering are called anchoring engineering.
