摘　　要：大藤峡水利枢纽工程地质构造复杂,岩溶作用导致岩石形成独特的蜂窝状形态且岩溶影响随着深度增加逐渐减小。岩溶通道可能与江水相连,增加了基坑开挖时产生涌水的风险。对此,本文对岩溶区的涌水情况进行了深入勘探和分析,并基于所得数据,提出了具体可行的防渗建议,以确保后续施工的顺利进行。The engineering geological structure of Datengxia water conservancy project is complicated,and the unique honeycomb shape of rocks is formed by karst process,and the karst influence gradually decreases with the increase of depth.The karst channel may be connected with river water,which increases the risk of water gushing during foundation pit excavation.In this paper,the water gushing situation in karst area is deeply explored and analyzed,and based on the obtained data,concrete and feasible anti-seepage suggestions are put forward to ensure the smooth progress of subsequent construction.
