| 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 ro... |
