江口水电站椭圆型双曲拱坝体形特点

Figure characteristic of ellipse double-curvature arch damin Jiangkou hydropower station

江口水电站大坝为混凝土双曲拱坝,根据地形地质、几何约束及应力约束等条件,采用拱坝体形优化程序(ADASO)对拱坝体形进行优化计算,并经过经济、技术比较,最终选定为椭圆型双曲拱坝。

The dam of Jiangkou hydropower station is a concrete double-curvature arch dam. The optimization calculation of the dam figure uses the ADASO program according to the conditions of the topography and geognosy, the geometrical and the stress constraint. Then the elliptic double-curvature arch dam is selected through comparing the economy and technology.
