Embodiment
[0027] In this embodiment, the trapezoidal pyramid base plate and the common clay in Nanjing are used as examples for test simulation. The finite element model structure of the mortar base plate is as follows figure 2 shown.
[0028] Establish a finite element model of the seat plate structure and soil coupling in HyperMesh, such as image 3 and Figure 4 shown. The material of the mortar seat plate is TC4 titanium alloy, and its material performance parameters are shown in Table 1. The compacted hard clay is selected as the soil, and its material performance parameters are shown in Table 2. The soil model is 1.5-2.5 times the length of the seat plate.
