水布垭面板堆石坝面板变形及应力应变监测成果分析

Analysis on Monitoring Results of Deformation,Stress and Strain of the Face Slab of Shuibuya CFRD

介绍了水布坝面板堆石坝面板变形和应力应变监测成果,分析了面板主要变形及受力特点。实测表明,面板变形及受力情况复杂,面板变形及应力主要发生在施工及蓄水过程中,其沿坝轴线方向的变形及较大的坝轴向压应力是导致板间缝局部挤压破损的主要原因。

The monitoring results of deformation,stress and strain of the face slab of Shuibuya CFRD are introduced,and the main characteristics of the deformation and stress of the face slab are analyzed.The results show that the deformation and the stress of the face slab are complex.The main change of the deformation and stress of the face slab occur in construction period and impoundment period.The deformation and large compressive stress along the axis of the dam are the main cause of extruding rupture of joints between the face slabs.
