石兜水库大坝变形观测资料分析

Analysis on Deformation Observation Data of Shidou Reservoir Dam

通过对石兜水库大坝变形观测(沉陷及水平位移)资料分析,对石兜水库大坝库区水位、沉陷位移与平位移的关系进行了分析评价,分析结果表明大坝的垂直沉陷、水平位移变化量较小,大坝处于稳定状态。并在此基础上,对石兜水库大坝加高扩容提出了建议。

The paper analyzes and evaluates the relations between the dam level, subsidence displacement and horizontal displacement based on the monitoring data on dam deformation （subsidence displacement and horizontal displacement） in Shidou Reservoir; it is shown from analysis results that the vertical subsidence and horizontal displacement of the dam are much less, and the dam is being in a stable state. On the above basis, the paper proposes recommendations on the height increase and volume enlargement of Shidou Reservoir Dam.
