摘　　要：针对尼泊尔波迪·科西水电工程首部枢纽布置和软土坝基的岩性条件和渗透特征 ,通过对混凝土防渗墙深度、灌浆帷幕长度、混凝土渗透性、地基渗透性的敏感性分析 ,确定出防渗墙和防渗帷幕的优化方案 ,并对三种库水位工况下的三维渗流场进行了详细的计算分析 。According to the layout, condition of pebble foundation and character of permeability of Bhote Koshi hydroelectric project head works in Nepal, the optimal design plan of impermeable wall determined and grouting curtain was by analysis of sensitivity about the depth of concrete impermeable wall, the length of grouting curtain and the permeability of concrete and foundation, and also three dimensional seepage calculation under the conditions of three reservoir water levels was carried out. The result will provide the basic data for the optimal design.
