波动输入方法及其在水闸工程中的应用
Application of Seismic Motion Input Method in Sluice Projects
摘要
Abstract
The massless foundation model is usually used in most dynamic analyses of lock and culvert on soft foundation,but the effect of radiation damping of foundation is often neglected. On account of this problem, spring-damping element and seismic wave are applied on the boundary of the model with the finite program ADINA and viscous-spring boundary method. Meanwhile,the above method is adopted in seismic response analysis of a sluice-water-foundation system in our country. The results are compared to those of the traditional massless foundation model. It is found that the radiation damping of foundation can reduce dynamic response of sluice chamber effectively and the proposed method is proved precise and stable in calculating.关键词
