摘　　要：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 。Dam deformation pattern, developing trend as well as the influence of environmental factors upon dam deformation are analyzed as per dam deformation observation data in Shiquan Hydro Power Station. Statistic forecasting model is established for the key dam section, and dam deformation behavior is evaluated at last. The analysis shows that improvements shall be made for the deformation monitoring system to solve the problems such as too simple arrangement of dam deformation observation, datum point settlement of vertical displacement and low accuracy of horizontal displacement etc.
