摘要

基于心墙坝的渗流特性建立了渗流分析模型和坝坡渗透稳定分析模型，并进一步考虑坝下软土地基的压缩特性提出了与当前应力状态有关的软土层渗流分析模型，将所建模型应用于某水利枢纽主土坝典型软基断面不同运行工况的计算，详细分析了心墙的防渗作用和软土层变形对渗透稳定的不良影响。

Abstract

Based on seepage characteristics of core dams

seepage analysis model and dam slope permeability stability analysis model are established. And more

according to compression characteristics of soft ground under dam

the model of seepage analysis related to current stress state is also put forward. For different water level operating modes

the models are applied to calculation of typical earth dam section on soft foundation of a hydro-project. The effect of seepage prevention of core wall and the influence on seepage stability of soft clay layer are analyzed in detail.
