摘要

近年来,我国高速铁路建设迅速发展,越来越多的连续梁桥被修建于地震区。长联大跨连续梁桥相对一般桥梁而言,其动力特性及在地震作用下的响应更为复杂。以福建-厦门高速铁路上的乌龙江特大桥作为工程背景,研究长联大跨连续梁桥在地震区的地震响应规律,为桥梁的抗震设计方案提供依据。
In the recent years,the construction of high speed railways in China has attained quick development and more and more long span and long unit continuous girder bridges have been built on the railways in the seismic zones.Compared to other common types of the bridges,the dynamic performance and response of the long span and long unit continuous girder bridges under seismic action are more complicated.In this paper,backgrounded by the Wulong River Bridge on Fuzhou-Xiamen High Speed Railway,the laws of the seismic response of the type of the bridges in the seismic zones have been researched and the bases for seismic design of the bridges are provided.
