Abstract Based on geological structure data, we use the finite element analysis to construct the geometric model of the Wuzhishan station. Combined with the GPS and gravity observation results, we analyze the physical significance of the trend change of the fixed-point deformation observation data of Wuzhishan station. The study found that under the action of NNW-directed pressure, the deformation amplitude of the upper part of the model is significantly larger than that of the lower part, and when the lower part continues to shorten, it is easy to form an upper arch. Because the tendency of the rock formation tends to the southeast, the deformation trend also tends to dip to the southeast. This is consistent with the changing background trend of the existing observational data.
