| Abstract: | Friction pile gets friction from the undisturbed soil around it to brace its own weight and the loads from superstructure.The No.1 pier grade separation bridge and Jinxian connecting Liwen freeway and Jinxian over Zhegan railway is designed as a friction pile.According to the alteation work,the undisturbed soil around it was excavated with excavating machine.The pile sinded during construction.The causes of the sinking are analyzed from theory and technology,processing design scheme and the choice are introduced,and the main points of strengthing work also are given. |
