摘要：本文研究的主要目的是检测影响混凝土面板堆石坝（CFRD）面板开裂的影响因素之间的相互作用。首先严格模拟了施工和蓄水阶段的整个过程，其中堆石和堆石面板之间的相互作用使用弹塑性模型；使用现有的实验数据对模拟结果进行了校核。最后使用总应变裂缝模型模拟面板中嵌入的钢筋。分析结果表明，堆石的刚度随着面板上裂缝宽度的开展有显著变化，但没有到开裂的程度。增加配筋率是减小面板的平均裂缝宽度最有效的方法。堆石与面板之间接触面的性质和面板中钢筋的位置对面板开裂的影响不大。

Abstract：The primary goal of this study was to examine the relative effects of various factors that affect the cracking of the face slab of a concrete faced rock fill dam (CFRD). Rigorous simulation of the construction and impoundment stages were conducted in sequential phases during which the rock fill and the rock fill-face slab interface were modeled with elastic-plastic models that were calibrated to existing test data. The face slab was modeled using embedded reinforcements with a total strain crack model. The results of the analyses showed that the stiffness of the rock fill significantly changed the crack width on the face slab, but not the extent of cracking. Increasing the reinforcement ratio was the most effective remedy for decreasing the average crack width on the slab. The properties of the rock fill-slab interface and the location of the reinforcement within the slab did not significantly affect the cracking on the slab
