摘　　要：本文结合新疆吉林台面板堆石坝的一个设计方案 ,通过在面板和垫层之间不设置和设置接触单元等计算方案的结果比较 ,探讨较为理想的计算混凝土面板堆石坝面板应力和位移的三维有限元计算模型。计算结果表明 ,在面板下设置三维各向异性接触单元能得到比较合理的混凝土面板应力结果。This paper gives two kinds of models based on a design of Xinjiang Jilintai Concrete Faced Rock fill Dam. One is assumed to be inlaid three dimensional contact elements between the faceplate and the supporting layer. The other has nothing between them. The results show that the model with three dimensional contact elements is an advisable model for the analysis of stresses and displacements of faceplates.
