摘　　要：哈达山水利枢纽工程防护区堤基的卵石有局部集中现象,见有超径卵石(大于110mm),地质条件复杂。施工中堤基防渗处理措施采用复合防渗体形式的截渗墙。文中针对施工中因地层受阻,造成相邻水泥土成墙单元间存在缺漏或水泥土截渗墙底呈现台阶状无法形成连续整齐的水泥土截渗墙,进行有效的处理。复合防渗体达到了哈达山水利枢纽防护区的防渗要求,为社会经济发展提供了保障。The gravels have phenomenon of local concentration and oversized diameter(over 110m) in the dike foundation of the protected area of Hadashan hydro-junction,then the geological conditions are complex.The anti-seepage wall with composite anti-seepage body is used as anti-seepage treatment measure in dike foundation construction.Because of the formation hindered,there are gaps between contiguous cement soil units and step-likes at the bottom of cement soil anti-seepage wall,the paper introduces the method to treat effectively the discontinuous and irregular cement soil of ant-seepage wall.The composite anti-seepage body meets the anti-seepage requirement in the protected area of Hadashan hydro-junction,which could provide protection for the socio-economic development.
