摘　　要：开都河察汗乌苏混凝土面板砂砾石坝建在覆盖层上,坝高110 m,坝基砂砾石覆盖层最大厚度为46.7m, 在河床覆盖层处设置一道混凝土防渗墙防渗。文章对已建类似工程覆盖层地基的趾板结构型式进行了分类分析, 并对察汗乌苏水电站覆盖层上的不同趾板结构进行了应力应变分析比较,提出了合理可行的方案。The Chahanwusu concrete face rockfill dam will be built on the sandy gravel overburden on the Kaidu river, with a dam height of 110m and a maximum depth of sandy gravel overburden of 46. 7m. A concrete cutoff wall will be constructed at the overburden of the riverbed. The analysis is made of the structural type of plinth slab on the overburden for the completed hydropower stations, and the stress strain analyses and comparisons have been carried out on different plinth structure on the overburden for Chahanwusu Project, thus the reasonable and feasible scheme is put forward.
