考虑桩侧土软化的单桩性状计算分析

Research on behaviors of single pile considering softening of pile-side soil

在分析单桩桩侧土工作性状的基础上,提出了一种考虑桩侧土软化效应的荷载传递函数,分析了模型曲线随其中2个参数a和b的变化规律。将该传递函数应用于单桩性状的分析,与采用常规的双曲线型传递函数的计算结果进行对比分析对比结果表明,采用该模型计算出来的单桩承载力更合理和准确。

Based on analyzing performances of pile-side soil, a new load-transfer function considering the softening is presented. The shapes of the model curve with three parameters a and b in the model are presented. The new transfer function is applied to simulate the behavior of single pile. The results from softening function are compared with those from conventional load-transfer function; and some conclusions are drawn.
