| Abstract: | To analyze the bearing capacity mechanism of a tapered cast-in-situ pile,a numerical simulation is made by FEM.The stress-strain characteristics of the soil around the pile and the load transfer mode of the tapered cast-in-situ piles are studied with the stress of soil besides the piles changed and the thickness of the sedimentation increased.The research could provide a reference for the bearing capacity design of the tapered cast-in-situ piles. |
