摘要
观音岩水电站拦河坝高82．10m，为细石混凝土砌块石双曲薄拱坝．经多方案设计比较并结合结构模型试验，选用了双圆弧变厚度拱体形的双曲拱坝，使坝体厚度与应力分布的大小相适应，同时设置了内部及外部监测系统，以监视拱坝的运行状况。
Guanyingyan Hydropower Station is located on upstream of Wuyanghe riverwhich is a tributary of Yuanshui river belonging to Dongting water system. Its dam is a dou-ble-curvature thin arch dam made of block stone masonry using fine aggregate concrete, witha height of 82. 1 m. Compared with many design proposals and considered the results of mod-el test, the proposal of double-curvature arch dam composed by a set of .Variable-thicknessarches taken shape by double circuIar arcs was selected in order to make the thickness of damsuit the distribution of stress. Monitoring systems inside and outside are also considered inthe design.
