Taking a certain wharf project for example,the transverse bent is considered by the flexible pile platform,the actual structure diagram is simplified and the simplified calculation diagram is obtianed.Based on the m method and hypothetical embedded point method，we use fixed end constraint modeling and elastic build-in modeling respectively to simulate the pile-soil interaction.Two kinds of finite element model are established based on ANSYS to calculate the internal force and deformation of the transverse bent frame under the horizontal force.Finally,SPSS statistical analysis is carried out on the calculation results.The results show that when the significant level α is taken as 0.05,there is little difference of influence on the internal force and deformation of the transverse bent frame under the horizontal force when using m method and hypothetical embedding method to calculate the pile-soil interaction.
