招徕河水电站碾压混凝土双曲拱坝设计

招徕河水电站拱坝位于极不对称的“V”形峡谷中 ,最大坝高 10 7m ,顶厚 6.0m ,底厚 18.5m ,厚高比 0 .17,系水平向变厚、变曲率中心的对数螺旋线型混凝土双曲薄拱坝。在充分考虑坝址的水文气象、枢纽布置、筑坝材料和施工条件的基础上 ,采用碾压混凝土筑坝新技术。简化坝体构造、施工工艺和温控措施 ,缩短了建设周期 ,节省了工程投资。

Design for RCC Double-curved Arch Dam of Zhaolaihe Hydropower Station

Zhaolaihe dam, situated in an extra-unsymmetrical vally, is a logarithmic spiral double-curved thin arch dam with the maximum height 107 m, crest thickness 6.0 m, base thickness 18.5 m, ratio of thickness to height 0.17. In consideration of the topographical, hydrological, meteorological and constructional conditions at the dam site, the dam is built with RCC technique, so the construction progress is quickened and the construction expenses is cut down.
