摘要
埃塞俄比亚泰可则(TEKEZE)水电站位于该国西北部泰可则河中游Tigray区80 km以西的Mekele地区,其大坝为混凝土双曲拱坝,最大坝高185 m,最大底宽27.94 m,最小顶宽约5.6 m,坝顶弧长420 m,其宽高比小于0.2,为目前世界上最薄的双曲拱坝。因该工程设计由Harza国际工程咨询公司承担,其配合比设计要求与国内的设计不同,从配合比设计入手比较了国内和国外混凝土拱坝配合比设计的差异。
Ethiopian Tekeze Hydroelectricity Station is located in Mekele district, 80 kilometers west to the Tigray District in the midstream Tekeze River in the northwest Ethiopia. The dam is a kind of the concrete double arch dam, with the maximum height of 185m, and the maximum bed width of 27.94m, the minimum crown width of 5.6m. The arc length is 420m, and the ratio of width to height is less than 0.2, which makes it be the thinnest double arch darn in the world. This project was designed by Harza International Development Co. and the concrete mix ratio design requirement was different from that practiced in China. The difference between the two systems has been studied, bridging the gap between the internationally accepted practice and the domestic one after China＇ s entry of WTO.
