混凝土面板堆石坝运行期存在的渗流问题及成因研究综述

混凝土面板是作为面板堆石坝的主要防渗结构，承受较大的水头落差，其对于坝体渗流的安全稳定性至关重要，但是在运行期常存在一些渗流问题。本文在研究混凝土面板坝运行期渗流安全的基础上，分析了国内外混凝土面板坝渗流破坏的典型案例，总结了面板破坏的主要渗流问题模式，包括裂缝渗流、局部破损渗漏和防渗设计缺陷渗漏等，并在此基础上，对不同破坏模式的成因进行了分析，研究成果可为同类工程防渗设计及渗流控制提供参考。

Research on seepage problem and character of concrete face rock-fill dam under operating period

As the main anti-seepage structure of concrete face rock-fill dam,concrete face bears high wa-ter-head,which is vital to the seepage stability and safety of the dam. However,there are often some seep-age problems in the operating period. In this paper, in order to research the seepage safety for concrete face rock-fill dam, some typical seepage damage cases of concrete face dam both at home and abroad are analyzed. The related main damage modes are then summarized, such as cracks, local broken region and structural design problem. On this basis, the seepage causes of the dam under various damage modes are analyzed. The results can provide a good reference of the seepage control design for similar projects.
