摘要

在土石坝混凝土结构周围设置一定范围的高塑土可以控制防渗墙改善应力集中、控制可能发生的裂缝。对设置不同高塑土区域心墙堆石坝进行有限元计算分析比较，结果表明，在廊道和主防渗墙顶局部设置高塑土，比沿心墙底部通长布置更能改善混凝土结构应力。心墙底高塑土区域设置过大，反而会使得原来局部设置高塑土分散的坝体荷载重新调整，从而导致廊道和主防渗墙的应力增加。

Abstract

Highly plastic clay is usually used to control the cracks produced by the stress concentration around the concrete structure in the rock fill dam. Numerical analysis is preformed on different highly plastic zones in a rock fill dam using the finite elements method. The FEM calculation results have shown that the installation of highly plastic soils on the top of gallery and major diaphram wall can better improve the structural stress of concrete than the full-length installation of the soil along the core bottom. Too large area installation of highly plastic soils in the core bottom will make the originally dispersed loads on the dam body caused by the local installation of soils readjusted

thus increasing the stress of the gallery and the major diaphram wall.
