Description

Building foundation anti-seismic structure Technical Field The utility model belongs to the technical field of building structures, and particularly relates to a building foundation earthquake-resistant structure. Background In the construction engineering, the pile is used as a core force transfer member between the building and the foundation, and the stability directly determines the earthquake resistance and long-term safety of the whole building. At present, most of piles widely used are cylindrical structures and are vertically inserted into foundation soil layers to bear vertical loads. However, the traditional pile has the obvious defects that when the earthquake induces transverse acting force, the contact area between the pile and surrounding soil is limited, the surface smoothness of the pile is high, and the friction resistance and the occlusion effect of the pile-soil interface are insufficient. Under the working condition, the pile is easily influenced by horizontal shearing force to generate lateral displacement, incline and even be pulled out, and the overall stability of the structure is seriously weakened. Although attempts have been made in the prior art to increase the load carrying capacity by increasing the pile diameter or using a form such as a pedestal pile, it is mainly optimized for vertical loads with limited improvement in the transverse shear performance. While the surface roughness of the partially improved piles (such as screw piles and special-shaped section piles) can be increased, the construction is complex, the cost is obviously increased, and the large-scale popularization and application are difficult. Therefore, how to effectively improve the transverse shearing resistance and the pulling resistance of the pile under the premise of ensuring the convenience of construction is still a technical problem to be solved in the field.
