天生桥一级水电站面板坝坝体变形特征

The deformation features of the dam body of concrete facing rockfill dam of Tianshengqiao First cascade Hydropower Station

天生桥一级水电站混凝土面板堆石坝施工期和初蓄期坝体的沉降、水平位移、坝体与面板的脱空、上游坝坡裂缝、混凝土面板的变形和变位、坝体表面变形等变形特征 ,既有堆石坝的共同特征 ,也有其自身的特征。对其进行观测、分析研究 ,对混凝土面板堆石坝的设计和施工有一定的参考价值。

The deformation characteristics of the concrete facing rockfill dam for Tianshengqiao First cascade Hydropower Station during its construction period and initial impounding period, such as settlement of dam body, horizontal displacement, cavities between dam body and face slab, cracks on the upstream dam surface, the deformation and deflection of concrete face slab, surface deformation of dam body, etc , have the common features of earth rock dam as well as itself features The results of observation, analysis and study on such characteristics will be used in the design and construction of concrete facing rockfill dam for reference
