| Abstract: | Based on the study of variation method of pile foundation with rigid raft, the computational method for composite pile foundation under elastic cap was given by introducing thin elastic plate element, and the influence on composite pile behavior of cap rigidity variation was considered furthermore. A simple engineering example was computed by this method. It showed that the variation of cap rigidity can cause remarkable changes with load bearing ratios of soil and pile group respectively. |
