普定水电站运行初期大坝变形观测情况

Results of Dam Deformation Observation of Puding Hydropower Station during Its Initial Operation Period

普定水电站碾压混凝土拱坝是目前国内首座、世界最高碾压混凝土拱坝， 对其运行初期变形进行观测是从一个侧面判断其施工方法优越性和可靠性， 为科学研究积累和提供资料的重要手段。本文介绍了大坝变形监测系统中的监测控制网部分， 通过观测分析统计， 得出了拱坝没有发生影响安全的异常位移， 坝体稳定，

RCC arch dam of Puding Hydropower Station is the highest one in the world,the first one in China.Its deformation observation during its initial period is an important method to insure the safety of the dam.The paper introduces supervision control network of dam deformation supervision system.Analyzing the observation data,the writer deduces the conclusion that the stability and deformation of the dam are normal and unusual deformation of the arch dam,which could affect its safety,has not occurred.
