| 摘 要： | 招徕河水电站混凝土双曲拱坝位于极不对称的“V”型峡谷中,最大坝高109.5m。与二心圆双曲拱坝的体型优化比较,对数螺旋线型拱坝具有对两岸坝肩稳定有利、减小坝体应力、节省工程量等优势,被选定为推荐的拱坝体型。应力分析成果表明:变厚、变曲率中心的对数螺旋线型混凝土双曲拱坝,由于应力分布均匀、主拉应力值小且范围不大、拱推力方向合理,是适应极不对称河谷地形的理想拱坝体型。

| Abstract: | Zhaolaihe Dam is situated at an unsymmetrical Valley. The Comparison between Logarithmic spiral arch dam and two-centered arch ones shows that the former is more suitable for the landform in site than the latter, because the stresses in the former dams are well-distributed and the stability of dam abutments is favorable. |

| Keywords: | Zhaolaihe Hydropower Station logarithmic spiral double-curved arch dam optimizing design |
