混凝土面板堆石坝潜没式混凝土高趾墙设计

Design of submerged concrete high toe wall of CFRD

混凝土面板堆石坝的设计中,通常采用混凝土高趾墙的方式来弥补地形、地质条件的缺陷或处理与岸边相邻水工建筑物合理衔接问题。根据黄河公伯峡水电站、新疆察汗乌苏水电站混凝土面板堆石坝高趾墙的设计研究,将这种部分墙体位于库水位以下的混凝土高趾墙称为潜没式高趾墙,同时对潜没式高趾墙的体型设计、稳定应力计算等问题提出一些意见和看法。

In CFRD design, concrete high toe wall is usually adopted to remedy defects of topographical and geological conditions and to connect adjacent hydraulic structures on the bank. Based on the design of concrete high toe wall of CFRD for Gongboxia hydropower station on the Yellow River and Chahanwusu hydropower station in Xinjiang, the concrete high toe wall partially located under the reservoir level is called as submerged high toe wall. The paper puts forward some recommendations on the shape design of submerged high toe wall and stability stress calculation.
