摘要

应用黏-弹性人工边界于双江口土石坝的动力响应分析中，考察了黏-弹性人工边界及地基辐射阻尼效应对土石坝动力响应的影响程度。计算果表明，该方法比传统的固定边界无质量地基下的大坝加速度动响应结果降低了15%~30%，在土石坝的动力响应分析中应当予以重视。

Abstract

Applying viscoelastic artificial boundary to dynamic response analysis of Shuangjiangkou rock-fill dam

the effect degree concerning earth-rock dam dynamic response based on viscoelastic artificial boundary and the radiation damping effect of foundation is evaluated. The result shows that comparing with traditional solid boundary massless foundation the method decreases the dynamic response result of acceleration by 15%~30%. It should be taken into account in the dynamic response analysis with regard to the rock-fill dam.
