| Abstract: | Based on the theory of the shear\|swelling failure,and considering the friction on the interface between pile and soil,the limit bearing capacity of the non\|uniform pile with bulk material and the composite foundation are studied by the numerical analysis method based on the earth mechanics theory.The influence of the pile shape and the friction angle of the interface on the limit bearing capacity is discussed by an example.It indicates that the bearing capacity of the composite foundation and the stress ratio of the pile\|soil may be increased and reduced respectively by optimizing pile shape. |
