台湾海峡跨海大桥抗震设计的思考
|
摘要
台湾海峡大桥是21世纪的一项伟大工程,由于台湾海峡所处的地质条件和台湾海峡跨海大桥的功能作用,台湾海峡大桥的抗震设计十分重要。本文分析比较了各种大跨桥型的抗震特点,并讨论了地震地面运动的空间性对各桥型地震反应的影响,进而提出了台湾海峡大桥在方案比选时应注意的一些抗震设计问题。
The Bridge across the Taiwan Strait is a great project in 21 century. Because of the geological structure of the location and the importance of the bridge, the seismic design of the bridge is very important. The characteristics of earthquake resistance of different types of large-span bridges are compared in this paper. The effects of spatial variability of earthquake ground motion on seismic responses of large-span bridges are also discussed. Some considerations of seismic design for the bridge across the Taiwan Strait in the stage of project selection are presented.
