摘要

混凝土防渗墙是近年来在病险水库加固工程中应用较多同时又存在不少争议的一项技术。笔者利用三维快速拉格郎日数值分析的方法，对采用混凝土防渗墙加固土石坝的加固效果及其运行状况进行了研究，分析比较了刚性混凝土防渗墙及不同弹模的塑性混凝土防渗墙在稳定、防渗等方面的差异，为该项技术的发展应用提供了参考。

Abstract

The concrete cutoff wall is a technology used in reinforcing sick dams more usually in recent years. The advanced FLAC3D method which is based on 3-D explicit finite difference method

is used to simulate the effect and working state of earth-rock dam reinforced by concrete cutoff wall. At the meantime

the differences in the stress and strain etc. between the rigid and plastic cut-off wall are also researched; and then that provides the reference to the use and development of this technology.
