溪洛渡水电站主要由拦河大坝、引水发电建筑物、泄洪消能建筑物组成。拦河坝为混凝土双曲拱坝,坝后设水垫塘消能。大坝顶高程610米,最大坝高285.5米;坝顶中心线弧长698.09米,拱冠顶厚14米,拱冠底厚69米。坝址地区基本地震烈度8度,按100年基准期0.02超概率确定抗震设防标准。计算和试验成果表明:在静载作用下,拱坝应力分布良好,满足容许应力要求。拱坝坝肩稳定及整体稳
Xiluodu Hydropower Station mainly by the dam, diversion power generation buildings, flood discharge energy-saving buildings. Dam for the concrete double curvature arch dam, water cushion pond dissipating energy. The crest elevation is 610 meters and the maximum dam height is 285.5 meters. The arc length at the crest of the crest is 698.09 meters, the top of the crown is 14 meters, and the bottom of the crown is 69 meters. The basic seismic intensity in the dam site is 8 degrees, and the seismic fortification standard is determined according to a 0.02-probability over 100-year benchmark period. The calculation and test results show that under the static load, the stress distribution of arch dam is good and the allowable stress is satisfied. Arch dam abutment stability and overall stability
