| 摘 要： | 文章针对混凝土面板堆石坝中面板和垫层间接触面上的变形机理与受力状态,提出了有厚度的节理单元,并建立了三维弹粘塑性接触面本构关系,它能够更加精确的模拟出接触面的张开、闭合和滑移等接触状态。还据此编制了有限元计算程序,利用此程序分析了一个具体工程实例,验证了该模型的合理性。

| Abstract: | This paper has put forward the theory of jointed element with certain thickness and established a 3D elasto-viscoplastic interface constitutive model according to the deformation mechanism and loading state of the interface between the concrete face and cushion of a concrete face rock-fill dam.It can accurately simulate opening,closing and slipping of the interface.In addition a finite element calculation program has been worked out.And a specific project has been analyzed as an example using the program to verify the rationality of the model. |
