汕头礐石大桥地震反应台阵建设简介
|
摘要
虽然大跨度斜拉桥正在被越来越多地采用,但其抗震理论和动力分析方法都尚处在探索之中,有待进一步验证和改进。汕头礐石大桥地震反应台阵的建成,为获取这类结构的地震反应数据,开展相应的研究提供了保证。从桥址的地震地质背景、台阵测点布设与设备安装、台阵的技术系统等方面的对地震反应台阵作了介绍。
Large-span cable stayed bridges are adopted increasingly,but some key technical problems of this kind of bridges have not been totally solved yet,whose anti-seismic theory and dynamic analysis are still under research and need to be validated and improved.The construction of Shantou Queshi Bridge seismic response monitoring network offers an opportunity to obtain seismic response data of large-span cable stayed bridges.The seismic geological background of the bridge site,distribution of stations,equipment settings,network technical system,etc.are introduced in this paper.
