茅坪溪防护工程是三峡工程的重要组成部分之一,它的运行性况如何是水利各界人士十分关心的问题,本文根据三峡水库蓄水前后的坝后渗流资料,讨论和分析了三峡水库蓄水至135·0m(最高蓄水高程139m)两个水文年的渗流特征。认为三峡水库蓄水到高程135m期间,验证了设计方案的正确性,也检验了茅坪溪防护大坝防渗施工质量较好,为三峡水库蓄水至156m提供了翔实的资料。
The Maoping River protection project is one of the important components of the Three Gorges Project. How it operates is a matter of great concern to people from all walks of life. Based on the seepage data before and after the impoundment of the Three Gorges Reservoir, the paper discusses and analyzes the impoundment of the Three Gorges Reservoir Water to 135 · 0m (maximum water level of 139m) two hydrological years of the seepage characteristics. It is verified that the design scheme is correct during the impoundment of the Three Gorges Reservoir to an elevation of 135m, and the quality of anti-seepage construction of the Maopingxi Dam is verified to provide detailed information for the impoundment of the Three Gorges Reservoir to 156m.
