摘　　要：论述了天生桥水电站副坝基础塑性混凝土防渗墙的设计和施工特点,针对古河道深厚覆盖层的地质条件,采用塑性混凝土防渗墙的防渗型式,结合有限元计算和配合材料试验,提出了塑性混凝土防渗墙的配合比,采用人工成槽和机械成槽并举,成功解决了基础防渗问题,取得了显著的效果。Design and construction characteristics of plastic concrete cut offwall in the auxiliary dam foundation of Tianshengqiao hydropower station were expounded in the paper. According to the geological conditions with deep overburden layer of ancient fiver course, the plastic anti-seepage concrete wall was adopted. By Combining with finite element calculation and materials mix test, the mix proportion of plastic anti-seepage concrete wall was proposed. Furthermore, artificial combined with mechanical groove-forming was adopted. The problem of anti-seepage was solved successfully for engineering foundation, which achieved obvious effects may provide some reference for similarprojects.
