| Abstract: | Composite pile foundation, which accounts for the bearing strength of pile and soil under pile cap together, is one type of pile foundation, and has been widely applied in coastal area. In this paper, finite element model for composite pile foundation has been established when applying vertical load and mechanical behavior of composite pile foundation have been analyzed. Furthermore this paper reveals effect of pile spacing on the composite pile foundation. |
