通过对大坝各个截面的平面应变分析，需要进行大量的判断来估计狭窄峡谷中大坝的整体三维动力响应。因此，本文的目的是提出一个三维和二维动力分析的结果之间的比较与不同的峡谷几何形状的两个大坝。从这个比较的条件下，三维行为是一个大坝的动态响应的重要性被确定。此外，二维分析的适用性，确定在陡峭的壁峡谷大坝的动力行为进行了评估。
Considerable judgment is required to estimate the overall three-dimensional dynamic response of a dam in a narrow canyon from plane strain analyses of individual sections of the dam. Accordingly, the purpose of this paper is to present a comparison between the results of three-dimensional and two-dimensional dynamic analyses of two dams with different canyon geometries. From this comparison the conditions under which three-dimensional behavior is of importance in the dynamic response of a dam are determined. Additionally, the applicability of two-dimensional analyses for the determination of the dynamic behavior of dams in steep walled canyons is evaluated.
