Abstract:

A series of model tests were conducted to study the bearing behavior of vertically loaded single inclined pile embedded in sand. The influence of the pile inclination angle on the load-settlement curve, axial force, bending moment, shear force and skin friction was analyzed. The test results show that the settlement of inclined pile is greater than that of vertical pile, the settlement of the inclined pile increases with the inclined angle; the axial force of inclined pile is less than that of vertical pile under the same pile head load and the reduction rate of axial force along the inclined pile shaft increases with the inclined angle; the bending moment mainly occurs in the upper half of the pile, which increases with the pile head vertical load and inclined angle; the distribution of skin friction can be divided into 3 segments regardless of the inclined angle, in which, the skin friction of the inclined pile reduces with the inclined angle in the first segment, the skin friction of the inclined pile increases with the inclined angle in the second segment, and the skin friction reduces with the inclined angle in the third segment.
