Abstract: Xiluodu arch dam, 285.5 m in height, is known as one of the highest arch dams in the world. This high arch dam faces complex situation while experiencing the deformation, temperature and stress changes during construction period. Therefore, there is a need to make a timely analysis on the monitoring data and a preliminary evaluation on the working behavior of the dam, as well as to give feedback of the analysis result to improve the design and guidance over construction.

Key words: Xiluodu dam, monitoring during construction, working performance

摘要： 溪洛渡大坝坝高285.5 m，是世界上最高的拱坝之一。作为高拱坝，其施工期的变形及温度、应力变化均较为复杂，因此应及时分析监测数据，对大坝工作性态进行初步评价，并将分析成果反馈设计，便于指导施工。
