摘要
Abstract
The self-balancing method currently faces several limitations,including incomplete conversion curves,overly conservative calculation results,and difficulty in obtaining analytical solutions,which limits its practicality.This paper proposes a novel method for determining the bearing capacity of single piles.It uses finite difference software and is based on the measured data of the self-balancing method to fit and invert the axial force and displacement data of the self-balancing test pile body,applying the parameters of the inverted soil layer and contact surface to traditional static load numerical simulation for positive analysis,thereby generating a complete load-displacement curve,and then calculate the bearing capacity of a single pile.By comparing the static load curve obtained by this method with the measured static load curve,the results show that the difference in calculated bearing capacity is within 5%,and the static load curve obtained by this method fits well with the measured static load curve,demonstrating high accuracy.关键词
