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.

该项目的目标是 进一步了解 线弹性地震 连拱坝的性态 水平与 目前存在的重力和 单拱坝，因此， 正在进行的重大差距 大坝的研究工作- 地震问题。 议题 将被调查包括 确定重要 动态行为的特征， 力传递机制、效应 水和地基 相互作用，量化 地震应力 地面运动和方法 改造，如交叉支撑。 该研究将集中在两个 现有的水坝将被用作 案例研究。 力振动 试验和重大地震 记录可用于其中一个 水坝，这些将被用于 进行比较和对比 分析。
