Abstract
In order to explore the frictional behavior of pile-soil interface,the direct shear of three pile-soil interfaces,i.e.concrete-soil,steel plate-soil,HDPE-soil are separately tested indoor,in which,6 normal stresses are applied.The results show that shear strength of pile-soil interfaces increases with vertical pressure increased;under the same normal stress,shear strength-displacement curve of each interface does not change much in the initial section,but it changes significantly in the latter section with the increase of stress;when normal stress is small,shear strength of each interface does not change much;when normal stress is larger,HDPE-soil interface has the maximum shear strength.关键词
