Abstract In view of the low efficiency and low automation of the traditional geotechnical engineering geological survey construction quality control method, this paper puts forward the construction quality automatic control method of geotechnical engineering geological survey. The finite element model of geotechnical engineering geological investigation is established by using CRM geological model transformation method. According to the numerical analysis method, the boundary area is cut, and according to the characteristics of the geological model, the volume mesh model is generated by multi-spatial domain method, and the generated model is imported into the finite element analysis system. The finite element model of automatic control platform of full hydraulic core drilling machine is designed. The drilling pressure control method is used to control the drilling pressure in the process of measurement, and the rammed expanded pile with composite carrier is used for construction. The experimental results show that the method can establish the finite element model with high speed and precision on the basis of realizing the automatic control of the construction quality of geological survey in geotechnical engineering. The utility model has the advantages of high precision, small size, strong anti-interference ability, and low cost. Keywords Geotechnical engineering . Geological survey . Construction . Quality .

Introduction At present, with the continuous acceleration of geotechnical engineering construction, there are higher requirements for the construction quality. In order to ensure the construction quality, it is of great significance to do a good job of geological survey before construction, which can not only lay a good foundation for the following construction and ensure the safe and orderly construction of engineering construction but also effectively improve the overall construction quality of geotechnical engineering. How to effectively control the quality of geotechnical engineering geological investigation has become an important research direction.

Xu Nengxiong et al. used a multi-mapping grid to mesh the complex tectonic rock mass (hexahedron) for the profile-based geological model. Wang Chunxiang et al. used the L-W topology model to search for key points at the ground level, and then combined with the control points of the structure to form the data points of the geometric model.
