摘　　要：采用三维有限元分析方法,利用通用有限元软件ADINA建立花坪河面板堆石坝三维有限元模型,分析了蓄水期坝体及面板各部分应力、位移分布,同时考察了面板接缝之间的变形特性。计算结果表明:坝体全部处于受压状态,下游坝坡附近存在低压应力区;面板中部主要为受压状态,在两岸岸坡附近为受拉状态;面板发生张拉变形的垂直缝主要集中在两岸,周边缝变形全部为张拉变形。Using general finite element software ADINA, we built three-dimensional finite element model of Huaping River Face Rockfill Dam by the three-dimensional finite element analysis method. Taking the loads that dam suffered in impounding period for an example, the stress and dis- placement distribution of dam and panel＇s various parts were given, and the deformation properties between the panel seams were also presented. The results show that ： the whole dam is entirety in a state of compression, and it exists the low-vohage stress zone near downstream slope ; the panel central is in the state of compression, and the vicinity of the two sides bank slope in the state of tension ; the panel vertical seam in tension deforma- tion mainly occurs in the both sides, and the peripheral seam is all in tension deformation.
