根据石泉水电厂大坝变形监测资料 ,分析了坝体变形规律及发展趋势 ,探讨了各环境量对坝体变形的影响 ,并就重点坝段建立了统计预报模型 ,最后对大坝的变形性态做出评价。分析认为 :石泉大坝变形观测布置过于简单 ,又存在垂直位移基点下沉 ,水平位移观测精度偏低等问题 ,应尽早完善变形监测系统
According to the deformation monitoring data of dam in Shiquan Hydropower Plant, the deformation rules and development trend of the dam body are analyzed. The influence of each environmental quantity on the deformation of the dam body is discussed. The statistical forecast model is established for the key dam section. Finally, the deformation of the dam State to make comments. Analysis shows that: the Shiquan dam deformation observation layout is too simple, there are vertical displacement base point sinking, horizontal displacement observation accuracy is low and so on, should improve the deformation monitoring system
