摘　　要：根据试桩资料的分析 ,指出了桩周不同位置的土体表现出不同的工作性状 ,单单依据桩的类型以粘性土的液性指数和砂性土的孔隙比等物理指标来确定桩侧土的极限阻力与实测结果往往存在很大的差异 。Through analysis on the testing result,it concluds that the working character of soil around pile are different because of its position and the test pile side resistance value are different from that of the value based on the physic index. It is necessary to build a new method to calculate the whole pile resistance.
