| Abstract: | The mechanical characters of composite foundation with capped rigid piles have been analyzed by means of finite element method(FEM).The change rules of the mechanical characters of the composite foundation have been researched.The equal settlement section of rigid pile with cap composite foundation has been proved.The results provides a theoretical base for the establishment of a calculation model for the composite foundation settlement,and a useful guidance for the engineering construction and design. |
