Abstract: In this paper ,a practical project with hand-dug cast ￣in-situ pile foundation is introduced. The results of pile static load test and dynamic test showed the insufficency of pile vertical bearing capacity and the shaft defect problem. Based on the test ,geological conditions and construction material , remedical measures were adopted after comprehensively analysing the accident causes. In treating the problem , pile-soil interaction was taken into account. The good effects of use and economy were gained.
