摘　　要：根据乌东德水电站垂线监测结果,定性、定量分析了乌东德拱坝蓄水初期水平位移演化过程及物理规律,进而评价乌东德水电站在蓄水初期的工作性态。结果表明,拱坝及坝肩变形均符合一般规律,处于正常工作状态。水荷载对变形起主导作用,同高程拱冠梁坝段径向变形最大,两侧坝段径向变形基本对称。与同类高拱坝相比,乌东德拱坝整体变形较小,其监测结果对未来超高薄拱坝设计及建设有重要参考价值。According to the monitoring results of the vertical line of Wudongde Hydropower Station,this paper qualitatively and quantitatively analyzed the evolution process and physical laws of the horizontal displacement of the Wudongde arch dam at the initial stage of impoundment,and evaluated the work performance.The analysis results show that the deformation of the entire arch dam and abutment conforms to the general law and is in normal working condition.The water load plays a dominant role on the deformation.The radial deformation of the arch crown beam dam section with the same elevation is the largest,and of the dam sections on both sides is basically symmetrical.Compared with the similar high arch dams,the deformation of Wudongde arch dam is smaller.The monitoring results have important value for the design and construction of ultra-high and thin arch dams in the future.
