插入式混合坝接头部位有限元静动力分析
FEM Static and Dynamical Analysis for the Connection of Inserted Type Mixed Dam
现如今对混合坝接头部位地震分析比较少。本文选择插入式混合坝对其进行研究，在混凝土刺墙与粘土心墙两种材料接触面上用极薄层单元来模拟，选用沈珠江弹塑性模型和等价非线性粘弹性模型。通过对混合坝进行有限元静力和地震计算，笔者详细分析了混合坝连接处各个接触面上的静动力反应，并给出了插入式混合坝接头部位抗震措施。
Nowadays,there are little analysis for the connection of mixed dam. In this article, inserted type mixed dam is selected to research. Paper elements are used to simulate the contact surface between concrete key-wall and clay core. Shen Zhu-jiang model and equivalent non-liner viscoelastic model are used. By FEM static and dynamical calculating, the author analyse the static and dynamical response on every contact surface of the mixed dam in detailand propose some earthquake-resisting measures.
