碾压混凝土大坝渗水控制措施探讨

Measures of seepage control in RCC dams

笔者首先阐述了碾压混凝土的施工特点以及采取措施进行渗水控制的必要性,然后以巴基斯坦高摩赞碾压混凝土大坝工程为例,对工程所采取的碾压混凝土坝体、层间结合和坝前防渗结构等渗水控制措施进行探讨,最后根据大坝蓄水运行后的渗水控制效果,得出所采取的渗水控制措施行之有效的结论。

The construction characteristics of RCC and the necessity of taking measures to control seep age are stated firstly.Then the measures of seepage control regarding RCC dam body,connection be tween layers and impervious structures on upstream dam surface are presented successively with the ex ample of Pakistan Gomal Zam dam project.At last,the conclusion is drawn that the applied measures for seepage control are effective,by analysis of the operation status since impounding of Gomal Zam dam.
