以南水北调大宁水库副坝混凝土防渗墙为例,采用二维非线性土石坝有限元计算程序,对其典型剖面进行了有限元计算,并分析比较不同材料及不同工况下防渗墙的应力变化,得出墙体的应力变形规律,优选出最佳的防渗墙材料,从而改善防渗墙的应力状态.文中还提出了防渗墙设计指标的合理范围,这对实际工程有重要的指导意义.

Taking the concrete cutoff wall in the auxiliary dam for Daning Reservoir for the South-to-North Water Transfer Project ag a studying case,a finite element calculation is made on the typical section of the wall based on the 2-D nonlinear finite element analysis program for embankment dam;in which the stress changes of the wall with different materials and under various operation conditions are compared and analyzed,and then not only the law of the stress-deformation of the wall is obtained, but the optimal anti-seepage materials are also optimized;by which the stress status of the wall is improved.Furthermore.a rational scope of the index for the design of the cutoff wall is also given herein,which can be taken as a reference for the actual project concerned.
