基于p-y曲线的基桩水平承载性状分析

Analysis of lateral bearing capacity of single pilebased of p-y curve method

基桩水平承载性状受到桩侧土体抗力特性、桩顶约束条件和桩身刚度特性等因素的影响.基于现场试验成果反演分析得到的成层土体的非线性p-y曲线,采用LPILE Plus软件分析了桩顶约束条件和桩侧土体抗力特性对桩顶位移和桩身弯矩的影响,并根据分析结果,提出一些建议,可供工程设计参考.

The lateral bearing capacity of single pile is influenced by soil properties,boundary conditions of pile cap and flexural rigidity of pile shaft.Based on the back-analysis results of p-ycurves for layered soil from field test data,the influences of boundary conditions and soil properties on lateral deflection and bending moments of pile shaft are analyzed.According to the analysis results,some suggestions are put forward to the designers for reference.
