摘要
水平位移观测是大坝安全检测的主要项目之一,该文对落坡岭水库大坝27观测点采用视准线法进行观测,并对观测水平位移实测资料进行分析,采用统计模型法对水平位移进行回归分析,模型精度较好,最后讨论了坝顶水平位移的变化规律及水位、气温和时效等因素对坝顶水平位移的影响。
The observation of horizontal displacement is one of dam safety inspection items, the 27 locations were observed by collimation line method in Luopoling reservoir dam. Regression analysis of horizontal displacement were simulated by statistical model based on observation data, the model has better precision. Finally, change rule of dam horizontal displacement and the main factors of water level, atmospheric temperature and aging effect affecting dam displacement were studied.
