摘要
针对堆石流变会引起200 m级面板堆石坝面板脱空、压坏等现象,采用沈珠江三参数流变模型对200m级混凝土面板堆石坝进行三维有限元计算,对比了不考虑堆石料流变的计算结果,并分析了堆石料流变特性对坝体和混凝土面板应力变形及面板接缝变形的影响。结果表明,堆石流变较大程度上改变了坝体和面板的变形与应力。
Rheological behaviors of rockfills can cause the face slab of concrete facing rockfill dam （CFRD） dislocated, crushed and other phenomena. The rheological model of Shen zhujiang＇s three parameters and finite element method are used to analyze CFRD with height about 200 m, By contrasting the results with not considering the rheological effects of rockfills, the influence of rehological behavior of rockfills on stress and deformation in dam, face slab and on the deformation of face slab joints are analyzed. The results show that the rheology of rockfills has greatly changed the deformation and stress of dam and face slab.
