【摘要】 以某三跨连续刚构桥为例,研究了深水作用下,连续刚构的地震反应,利用Midas-Civil建立全桥空间模型,考虑深水作用对其进行反应谱和动力特性分析,并同不考虑深水作用的工况进行了对比,分析得出,深水作用会对连续刚构桥在地震作用下的位移和内力产生较大的影响,尤其对主墩产生的影响最大,设计时应重点关注。更多还原

【Abstract】 Taking a three span continuous rigid frame bridge as an example,study the effect of the deep water on the earthquake response of continuous rigid frame.Make a full-bridge space model by "Midas-Civil" and perform the response spectrum and dynamic characteristic analysis considering the effect of deep water.And the role without deep water conditions is compared.Analysis,deep water can produce great influence on displacement and internal force of continuous rigid frame in the earthquake,especially on the main piers,which the design should pay attention to.更多还原
