摘　　要：土石坝体混凝土心墙与坝基混凝土防渗墙及混凝土重力坝段的联接是根据施工要求预先完成造孔防渗墙的浇筑,后续进行坝体施工时在原造孔防渗墙的基础上修建混凝土心墙,在现浇混凝土心墙和造孔防渗墙之间设置联接接头,同时在土石坝心墙与混凝土重力坝间设置联接接头。心墙联接技术的应用保证了心墙土石坝接头部位的防渗问题,广泛适用于混凝土心墙土石坝施工。The connection between the concrete core wall of the earth-rock dam body and the concrete anti-seepage wall of the dam foundation and the concrete gravity dam section is based on the construction requirements.For the core wall,a connecting joint is arranged between the cast-in-place concrete core wall and the hole-making cut-off wall,and a connecting joint is arranged between the core wall of the earth-rock dam and the concrete gravity dam。The application of core wall connection technology ensures the anti-seepage problem of the core wall earth-rock dam joints,and is widely used in the construction of concrete core wall earth-rock dams.
