In large-scale hydropower projects, the anti-seepage curtain is an important measure to reduce the leakage of reservoirs and ensure the stability of foundation rocks. In this study, an efficient procedure for the optimization design of an anti-seepage curtain was proposed given the drawback of the time-consuming and low efficiency in optimizing multiple parameters of the anti-seepage curtain. This procedure can dramatically shorten the time for numerical simulation, reduce the workload of planning multiple parameter sets, and effectively avert the probable distortion of optimized results to some extent. This is achieved by identifying and optimizing the parameter that has the greatest impact on the performance of the anti-seepage curtain on the premise of adequate geological investigation and proper qualification of the performance of the anti-seepage curtain. This procedure was applied to the optimization design of the anti-seepage curtain in the upper reservoir of a pumped storage power station. Four different depths were suggested for the anti-seepage curtain according to the optimization results. This procedure can serve as a reference for the optimization design of an anti-seepage curtain with high effectiveness and confidence.

在大型水电工程中，防渗帷幕是减少水库渗漏，确保基岩稳定的重要措施。在这项研究中，针对优化防渗帘的多个参数存在耗时且效率低的缺点，提出了一种优化设计的有效方法。此过程可以大大缩短数值模拟的时间，减少规划多个参数集的工作量，并在某种程度上有效避免了优化结果的可能失真。这是通过在充分的地质调查和对防渗窗帘性能的适当鉴定的前提下，识别和优化对防渗窗帘性能影响最大的参数来实现的。该程序应用于抽水蓄能电站上水库防渗帷幕的优化设计。根据优化结果，提出了四种不同的防渗帷幕深度。该程序可为高效，高信度的防渗窗帘的优化设计提供参考。根据优化结果，提出了四种不同的防渗帷幕深度。该程序可为高效，高信度的防渗窗帘的优化设计提供参考。根据优化结果，提出了四种不同的防渗帷幕深度。该程序可为高效，高信度的防渗窗帘的优化设计提供参考。
