渗透破坏是引起土石坝溃坝的重要因素，因此病险水库的防渗加固研究一直是土石坝的重要课题。昌黎水库自建成以来，坝坡发生流土、管涌等事故，下游居民的生命财产安全受到威胁。通过对防渗加固方案效果的比较，结果表明，混凝土防渗墙对该粘土坝的渗流状态有明显改善作用，具有较高的运行稳定性。因此，混凝土防渗墙是昌黎水库推荐的防渗方案。
Seepage failure is an important factor in causing dam-break of earth-rock dam, so the study of anti-seepage reinforcement for dilapidated reservoirs is always an important topic to earth-rock dam. Changli reservoir, since the completion, soil flow and failure by piping occur in dam slopes, the safety of downstream residents has been threatened both in life and property. Based on the comparisons of the effects of anti-seepage reinforcement schemes,the result shows that, for this clay dam, concrete cut-off wall can improve the seepage state obviously and has a higher operational stability. Thus, the concrete cut-off wall is designated as the recommended anti-seepage scheme for Changli reservoir.
