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 .
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 .
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 .
In this case , the bridge double piles structure has been widely used to protect the stability of the slope bridge plie foundation and the safety of adjacent environment , it is definitely a key problem for engineering design , that is how to accurately determine the internal force and displacement of such pile foundations .
