预应力管桩在饱和粉土中的荷载传递

Load transfer of pre-stressed tubular pile in saturated silty soil

对饱和粉土中的预应力管桩的荷载传递机理进行分析研究,分别用理想弹塑性双折线模型和基于硬化的弹塑性双折线模型模拟桩与桩侧土体和桩端土体之间的荷载传递函数,并提出参数选取方法,计算得到单桩P-S曲线。

The mechanism of the load transfer of the pre-stressed tubular pile in saturated silty soil is analyzed herein; in which the load-transfer function between the pile and soil bodies of both the pile side and pile end is simulated with the idea/bilinear elasto-plastic model and the hardening based bilinear elasto-plastic model respectively, and then the method for the selection of the parameters is put forward and the P - S curve of single pile is calculated as well.
