Abstract

Abstract

Based on the field test of pile foundation in Zhichuan river bridge, the bearing property of large-diameter over-length nonplacement pile in the area of powder sandy soil was studied, a comparison was made between the test result and the calculation value of empirical formula. It is pointed that there is a remarkable difference between the bearing property of large-diameter over-length nonplacement pile and that of medium length or short ones, when powder sandy soil is in different depth underground, its lateral resistance is different significantly, the bearing capacity difference of experimental piles and normalized formula is over 50%. The results show that the limiting lateral resistances of powder sandy soil of different depth are different, the normalized formula is not suited to evaluate the bearing capacity of large-diameter over-length nonplacement pile.
