Background

In the field of construction, buildings generally comprise a house structure and a foundation structure through which the house structure is built on the ground. The seismic performance of a building depends primarily on two aspects, one being the overall strength of the building structure and the other being the foundation structure supporting the building structure. When an earthquake occurs, seismic waves propagating in rock-soil cause vibration of the foundation structure, thereby causing deformation and strength change of the foundation structure. Once the strength of the foundation structure is insufficient to withstand the stresses caused by the deformation of the foundation structure, the foundation structure often fails, thereby losing its supporting ability. Most of foundation structures in the prior art are single in structure and fixed, and are poured in the original soil pit foundation on the ground, so that the earthquake resistance is low, and meanwhile, the structural stability is not sufficient, and the foundation structure is not beneficial to multiple earthquake zones.
