摘　　要：在渗流稳定性分析理论的基础上,采用SEEP/W软件和SLOPE软件研究了三峡库区某库岸边坡随库水位变化条件下的渗流和稳定性变化规律。研究表明,三峡水库蓄水到175 m水位时,虽然该岸坡不存在滑移失稳,但岸坡所处自然条件发生很大改变,由于波浪对库岸边坡的淘蚀作用,可能产生不同程度的塌岸,建议采取相应的护坡防护措施。On the basis of the theory of seepage stability analysis, SEEP/W and SLOPE are used to study the changing law of the seepage and stability varied along with the change of the water level of a bank slope within the Three Gorges Reservoir Area. The result shows that although the slope is not to unstably slide when the water level reaches 175 m in the reservoir, the natural environment is to be greatly changed, and then the bank collapses on various scales are to possibly occur due to the scouring effect from wave on the bank slope, thus several measures for the protection of the slope are suggested herein.
