金溪水电站拱坝变形性态分析

Analysis of displacement behavior for arch dam of Jinxi hydroelectric station

针对金溪水电站拱坝垂线水平位移实测资料建立回归模型,深入分析了金溪水电站拱坝的变形性态及变化规律。结果表明:金溪拱坝的水平位移变化符合拱坝变形的一般规律,整体变形性态较好,坝体变形处于弹性变形,工作状态基本正常。

Based on actual measured data of horizontal displacement in arch dam of Jinxi hydroelectric station, a regression model is established to analyze deeply the displacement behavior and rule. The displacement rule of arch dam of Jinxi hydroelectric station accords with universal displacement rule of arch dam. The whole displacement behavior of arch dam is preferable. The dam deforming is on elastic distortion, which indicate work status of arch dam is regular.
