The simulation of pile foundation is a common problem in practical design. Four common simulation methods are summarized: the original pile group model, the equivalent portal frame model, the single-column model and the support stiffness matrix method, and the equivalent model method which is widely used in the current planar rod system Applicable conditions. The pile foundation stiffness matrix method, with the help of the existing bridge structure space analysis software, has the advantages of simple and high efficiency modeling, convenient extraction of reaction force and wide applicability.
