截渗墙的应力应变三维有限元分析计算

Three dimensional finite element analysis for mechanical behavior of the diaphragm wall on the embankment

主要研究了截渗墙墙体上的水压力荷载分布、水位动态变化过程中墙体的应力变化、墙体的应力分析方法和应力分布规律等。结合南水北调东线工程中的双王城水库,根据不同的上下游水位差,分析截渗墙上下游面的水压力分布,作为截渗墙应力计算的基础。分析不同水位下截渗墙单元两侧表面的应力分布情况,找出其最不利的情况。

the wall at taking the In this thesis, the distribution of the water pressure on the diaphragm wall, the stress variation of the different water levels, the analysis method and stress distribution of the wall are investigated by Shuangwangcheng reservoir as an example. The distribution of the water pressure on two sides of the diaphragm wall at different water levels can be used to the base of the stress analysis. Then the stress distributions on the wall surfaces are analyzed.
