寒冷地区混凝土面板堆石坝面板的设计

混凝土面板堆石坝的面板受荷载作用时，发生弹性变形，产生内力，可将其视为弹性地基梁结构，进行结构分析．设计中应根据面板的受力特征进行分缝布置，选择合理的板厚，采用合理的结构配筋．对处于寒冷地区的混凝土面板堆石坝，要考虑冰冻对面板的作用和影响，重点考虑面板的抗冻问题．

Design of Face Slab of Concrete-faced Rockfill Dam in Cold Region

When the face slab of Concrete-faced rock fill dam (CFRD) is acted with loads, the elastic deformation occurs in it, which results in the inner forces. For structural analysis, it can be simplifized as an elastic foundation beam. In the design, it should be in accordance with the deformingfeatures of the face slab to layout the joints, choose the slab thickness and determine the rein forcementratio reasonably. For the concrete-faced rockfill dam in cold region, the attention should be paid tothe influence of icing action on the face slab, and the emphasis should be put on the freezing problemsof the face slab.
