【摘要】 针对混合坝接头部位地震分析比较少,笔者选择了插入式混合坝进行研究,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,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。更多还原

【Abstract】 Nowadays, there is little seismic analysis of the connection of mixed dam, hence the inserted type mixed dam is selected as the subject of this research. Paper elements are used to simulate the contact surface between concrete key wall and clay core, and Shen Zhu-jiang model and equivalent non-linear viscoelastic model are adopted. By FEM static and dynamic calculation, the static and dynamic response on every contact surface is analyzed, based on which the anti-earthquake measures are put forward in this article.更多还原
