建筑物纠偏地基应力解除法的有限元分析

Study of the Method of Subgrade-Stress Relieving Method Based on F.E.M. in Building Rectification

本文运用有限元对地基应力解除法纠偏进行了分析 ,通过对五种不同应力解除孔与基础边缘的距离对比分析 ,对地基应力解除法纠偏的定性概念和定量比较进行了数值验证 ,并简要介绍一工程反演实例进行了说明 ,以此来指出地基应力解除法纠偏应力解除孔布置方面应注意的问题。

In this paper,through the comparison of 5 different distances between stress relieving hole and the edge of the foundation,the method of subgrade stress relieving was analysed by FEM.The qualitative concept and the quantitive comparison was numerically investigatied.At last,a practical example was indroduced to point out some problems that attention should be paid in arranging the stress relieving holes.
