半中承式系杆拱桥设计与分析

Design and Analysis of Half-through Bowstring Arch Bridge

以秦汉大道灞河桥为实例,介绍了桥梁方案比选和半中承式刚性系杆拱桥的设计与分析,总结了该桥的一些技术特点和设计思想,同时介绍了高烈度区该类桥梁如何运用双向减隔震技术,并提出了尚须进一步研究的问题。

Taking Bahe River in Qinghan Avenue as an example,the article introduces the comparison and selection of bridge schemes,designs and analyzes the half-through rigid bowstring arch bridge,sums up some technical characteristics and design ideas of this bridge,introduces this kind of bridge how to apply the bidirectional seismic isolation technology in the high intensity area,and puts forward some issues to be further studied.
