It includes the analysis of grouting at pile bottom , the stress in soil mass around plie bottom induced by grouting , and the behavior of grouting piles under axial load .

该方法包括桩底灌浆分析，浆液渗透力在桩端周围土体中引起的应力分析，及在竖向荷载作用下桩的性能分析三个步骤。

The random vibration analysis is carried out for the wave response of the controlled structure , so that the expression of control effect of the TMD to the wave response of the single plie platform can be obtained .

在对受控结构的波浪响应进行随机振动分析时，考虑了流体-桩-土相互作用的影响。

Through analysing the structure and the process of driving plie , it is indicated that branches / plates not only make the bearing capacity area increased , the bearing capacity of single pile raised , but also make the end resistance reduced .

通过对支盘桩构造及成桩过程分析，支盘的设置不仅扩大了受力面积，提高单桩的承载力，而且还减少了桩端荷载，使支盘桩具有更大的承载潜力。

This paper explains the advances , economy , applicability and quality reliability of cement powder gushed plie in dealing with Q al 4 water sensitive yellow earth groundwork and the resulted significant economical benefits and social benefits through engineering practice .
