Earthquake Behavior of Multiple Arch Dams

该项目的目的是进一步了解多拱坝的线弹性地震行为，使其达到与目前存在的重力和单拱坝相当的水平。从而填补了目前大坝地震问题研究的一个重要空白。将研究的主题包括识别动力行为的重要特征，力传递机制，水和基础相互作用的影响，地震地震动产生的应力的量化，以及交叉支撑等加固方法。这项研究将集中在两个现有的水坝上，作为案例研究。其中一个大坝的力振试验和重要的地震记录可用，这些将用于比较和相关性分析。

The objective of this project is to gain further understanding to the linearly elastic earthquake behavior of multiple arch dams to a level comparable to that which currently exists for gravity and single arch dams, and so fill an important gap in the ongoing research effort on the dam- earthquake problem. Topics which will be investigated include identification of important features of the dynamic behavior, force transfer mechanisms, effects of water and foundation interaction, quantification of stresses generated by earthquake ground motion, and methods of retrofit such as cross-bracing. The study will focus on two existing dams which will be used as case studies. Forces vibration tests and significant earthquake records are available for one of the dams, and these will be used for comparison and correlation analyses.
