基于p—y曲线的侧向受荷群桩分析

On lateral load pile group analysis based on p—y curve

考虑群桩中桩—土—桩相互作用,分析了群桩中各排单桩的侧向受荷性状,用p—y曲线折减法模拟了群桩中桩土相互作用,分析了已有的群桩侧向受荷实验中群桩的荷载—变形性状及各排桩的荷载分配规律,并与实验值进行对比验证,结果表明,该方法计算简单,受力传递路径明确,分析结果合理。

Considering the pile-soil-pile interactive role in the pile group, the paper analyzes the lateral load pile group of the single piles of rows in the group, simulates the pile-soil mutual effect with the p--y curve reduction method, analyzes the loading-deformation performance and loading distribution law for piles in the lateral loading test of existing pile group, undertakes the comparative calculation with the experimental value, and proves by the result that the method has simple calculation method, identical force transfer channel and reasonable analysis result.
