Abstract

Abstract

The bearing capacity of friction piles depends on the shear characteristics of the pile-soil interface. In order to study the influence of moisture content and soil quality conditions on the friction resistance of friction piles, a test device for the pile-soil contact surface shear characteristics of friction piles was designed, and three types of silty clay, silt and fine sand were tested. There were 9 sets of laboratory tests on soil and three kinds of water content. The results showed that the lateral friction resistance of friction piles was hyperbolic with the settlement of the pile. The initial shear stiffness coefficient and the essential settlement for approaching ultimate lateral friction resistance were determined by the type of soil and the moisture content. The initial shear stiffness of fine sand was slightly higher than that of silty clay and fine sand with the same compaction coefficient; while the ultimate lateral frictional resistance of silty clay was higher than that of silty clay and fine sand with the same compaction coefficient; the ultimate frictional resistance of sand changed significantly, but it was relatively insensitive to the change of ultimate frictional resistance of silty clay, and the maximum value of the ultimate frictional resistance occured at the optimal moisture content.
