混凝土防渗墙在土石坝防渗加固中的应用

Application of Concrete Cutoff Wall in Reinforcement of Earth Rock Dam Seepage Control

土石坝的渗流安全问题在整体安全中占有重要地位,直接影响大坝的运行安全。混凝土防渗墙作为挡水建筑物加固防渗体系的主体部分,防渗效果最为可靠。文章在分析材料及其工艺的基础上,对土石坝防渗加固中混凝土防渗墙的设计、施工方法等问题进行初步总结。

Earth rock dam seepage safety problems occupy an important position in the overall security,directly affecting the safe operation of the dam. Concrete diaphragm wall as the main body of water retaining structure of seepage prevention and reinforcement system,anti-seepage effect is most reliable. On the basis of materials and technology analysis,the paper summarizes the problems on design,reinforcement of concrete anti-seepage wall in earth rock dam seepage prevention and construction methods.
