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。
Mainly studied the distribution of water pressure on the wall of cut-off wall, the stress changes of the wall during the dynamic change of the water level, the stress analysis method and the stress distribution law of the wall. Combined with Shuangwangcheng reservoir in the project of South-to-North Water Diversion Project, the distribution of water pressure on upstream and downstream of cutoff wall is analyzed according to different water level difference between upstream and downstream of the cutoff wall as the basis of stress calculation. Analyze the stress distribution on both sides of cutoff wall unit under different water levels and find out the most unfavorable situation.
