摘　　要：花凉亭水库大坝为黏土心墙砂壳坝,具有黏土心墙薄、坝坡面陡的特点,在施工中遇到穿透7～ 11m厚砂层问题.本文主要介绍针对此问题采取的处理措施.通过对防渗墙采取工程技术措施并对其施工质量进行检测,防渗墙防渗效果明显,可供其他水库工程参考.The Hualiangting Reservoir dam is a sand shell dam with clay core, thin clay core and steep slope surface. The problem encountered in its construction is passing through sand layer at 7 - 11 meters. This paper mainly deals with the treatment measures taken for the problem. Some engineering technical measures are taken for cut-off wall and its construction quality is inspected. The results show that the seepage control effect of the cut-off wall is obvious and may be available for references for other reservoir projects.
