| Abstract: | A three-dimensional finite element composite pile foundation model is established based on soil's elastoplasticity and contact properties between piles and soil by the finite element software to calculate and analyze systematically the changing trend of settlement and differential settlement under different loads,pile length,pile diameter,and pile space,and obtain the conclusion which may serve as a reference for the design. |
