摘　　要：本文针对滑坡体上修建防渗体难度大的问题,以山东省平原水库大坝复杂地质结构上建设防渗体为例,结合地质条件设计了坝基防渗加固方案,并通过模拟计算对大坝典型断面的渗流情况进行分析与评判。模拟结果表明,防渗处理后的大坝渗流量得到有效控制,渗流稳定,符合安全运行要求。In the paper, anti-seepage bodies constructed on the complex geological structure of Pingyuan Reserwir dam in Shandong are adopted as examples aiming at the problem of high difficulty of constructing anti-seepage bodies on landslides. Geological conditions are combined for designing a dam foundation seepage prevention and reinforcement plan. The seepage condition of dam typical cross sections is analyzed and evaluated through simulation calculation. Simulation resuhs show that the dam seepage flow after seepage prevention treatment is controlled effectively, seepage is stable, and the project is consistent with the requirements of safe operation.
