摘　　要：面板堆石坝的面板挠度变形破坏是面板坝的主要病害之一,其严重影响面板坝整个生命周期内的安全稳定运行。为此,通过介绍分析目前面板挠度变形监测的几种常规方法及其在实际使用过程中存在的问题,提出采用在面板内部埋设安装柔性测斜仪系统(SAA)来监测面板挠度的新方法,通过在国内某大型水利工程面板坝的实际应用,验证了该方法的科学性和合理性。该方法可获取高精度、连续、范围广的面板挠度变形数据,同时具有施工方便、易于保护、能够更换的显著优势。The panel deflection deformation is one of the main diseases of CFRDs,which seriously affects the safe and stable operation of CFRDs.Several conventional monitoring methods of panel deflection deformation of CFRDs are introduced and some problems in practice of monitoring methods are analyzed.A new monitoring method by embedding shape accel array(SAA)inside panel is proposed,and the scientific and rationality of the method is verified by the practical application of the method in a large-scale water conservancy project in China.The new method can obtain high-precision,continuous and wide range of panel deflection deformation data,and has obvious advantages of convenient construction,easy protection and replaceability.
