[0003] Pile foundation is a deep foundation that connects the top of several piles into a whole through a pile cap to jointly bear dynamic and static load. Pile is a vertical or inclined foundation component arranged in soil, which penetrates soft and high compressibility soil or water to transfer the load borne by the pile to a harder, denser or less compressible foundation bearing layer.

The connection mechanism of each foundation pile usually adopts simple connecting plate or pin type connection, which has low connection strength, insufficient shear resistance and is difficult to effectively ensure the stability and seismic performance between the foundation pile columns.
