Abstract: For the thick fill foundation, due to its effects of consolidation on piles, deformation, the pile negative side fricition can not be ignored. Based on the monitoring data of the actual project site, the distribution law of the negative side of pile friction in thick fill site is analyzed; and a simplified theory calculated figure of negative side friction linear distribution along the axial, and the negative side friction coefficient calculation method are proposed. Through the comparison and analysis of the monitoring data, the negative side friction coefficient in thick fill foundation is obtained about 0.09-0.15, which verifies the rationality of the method proposed for the rational design of similar site pile foundations.

Key words: thick fill, pile foundation, negative side friction
