摘　　要：对混凝土防渗墙、冲抓套井回填粘土防渗墙、多头小直径深层搅拌桩3种土坝坝身截渗施工方法进行比较,选择多头小直径深层搅拌桩,对均质土坝坝身进行加固。通过室内试验和现场检测证明了深层搅拌桩是既经济又有技术保障的防渗手段之一。Through the comparing the results from the three impervious construction of earth dam methods, concrete cut-off wall, rushed to grasp well the cutoff wall backfilled clay, multiple-start and minor diameter deep-mixing pile, The final version was multiple-start and minor diameter deep-mixing pile to homogeneous earth dam body for reinforcement. Through indoor test and field test proved that the deep mixing pile is economical and has one of the seepage control means of technical support.
