摘要
本文研究浪流冲击下圆柱－平台－土体－水流系统的动力响应问题。文中考虑了圆柱与水流和地基土之间的相互作用，由解析法给出了圆柱平台结构在浪流力激励下的动力响应分析，给出了具体算例的数值结果，并讨论了系统参数对动力特性的影响。
his paper deals with the problem of dynamic response of circular cylinder platformsoilwater system due to impact by water wave flow. Dynamic interaction of cylindersoilwater is taken into account and the analysis of dynamic response due to water wave force is given by analytic method. The numerical examples are presented and the influence of system′s parameters on the dynamic behaviour is discussed in the end of paper.,,
