摘　　要：采用非线性有限元方法,对某平原水库防渗墙的应力进行了分析.计算中考虑了坝体的施工过程、水压力的升高过程、先筑坝后建墙和先建墙后筑坝两种不同的施工顺序,计算结果表明墙体的强度是有保证的.Nonlinear finite element method is used to analyze the stresses and deformations of the cutoff wall of plain reservoirs, in which the construction process and the increase of the water pressure on the wall are considered, and the effect of two kind of construction sequence （the construction of the dam body first or that of cutoff wall first） is investigated. The results show that the strength of the cutoff wall is sufficient.
