Abstract: Based on the deformation of body and base of Dagangshan arch dam, the distribution characteristic as well as its development and change rule during initial impoundment is studied. Then its working behavior in storage period is analyzed. Monitoring results indicates that the deformation of body and base conforms to the general rule, and the numeric value stays in the designed control scope, which is worthy reference for other super-high arch dams.

Key words: Dagangshan arch dam, initial impoundment, analysis on deformation monitoring data

摘要: 根据大岗山水电站大坝及坝基变形成果,研究了大岗山混凝土双曲拱坝初期蓄水的变形分布特征和发展变化规律,分析了大岗山水电站蓄水期的工作形态。监测成果表明,大坝及坝基变形符合一般规律,量值在设计控制指标范围以内,其变形监测成果对其他特高拱坝具有重要的参考价值。
