某水库浆砌石坝渗漏分析及处理方案探究

Study on the Leakage Analysis and Treatment Scheme of A Stone Masonry Dam

以病险水库挡水建筑物为研究对象,结合工程实例,针对某水库浆砌石挡水坝右坝肩及坝基渗漏问题进行了研究,并从工程角度提出了有针对性的防渗处理方案,最后借助有限元软件对加固后的坝基渗流场进行了数值分析。结果表明,采用加固措施之后,坝基的渗漏量和下游渗漏出口处的渗透迫降均明显降低,满足工程正常运行的要求,这一处理方法可为类似工程提供参考。

The reservoir water retaining structure as the research object, combined with the engi- neering example for the study of the masonry dam right abutment and dam foundation seepage prob- lem of a reservoir, and from the engineering point of view are proposed in view of the seepage con- trol schemes ; finally, using the finite element software of foundation seepage reinforcement field nu- merical analysis. The results show that the reinforcement measures adopted after landing, infiltration leakage and downstream leakage at the outlet of the dam foundation were significantly reduced, to meet the normal operation of the project requirements, this method can provide reference for similar engineering.
