挤压效应下土体内响应场的非线性有限元分析

Analysis of the Response Field in the Soil Caused by Squeezing through Non-linear Finite Element

通过对土在挤压效应下的有限元分析,研究了土的应力场分布的规律,从而数值化地分析了挤扩支盘桩在挤扩成盘过程中挤压效应对相应土体的性状的影响范围,对支盘的间距设计提出可行性建议。

The distribution of the stress field and strain field caused by squeezing the soil are studied by the use of the finite element analysis.The influence space of the effect of squeezing on the correspondent soil during the course of plates being formed are numerically analyzed, which would provide feasible advices of the space for plates placed.
