浅谈城市轨道交通“桥-建结合车站”与区间接驳方式

对城市轨道交通高架车站结构"桥-建结合车站"中车站主体与区间桥梁接驳方式进行系统的调查与分析,按照现有的接驳方式分为:①车站边跨盖梁(桥式车站)、框架梁(框架式车站)设置牛腿;②车站边跨设置双柱,区间箱梁或"U"型梁与车站主体脱开。通过调查和分析,按照车站受力特性,结合车站建筑设备功能和要求,分析两种接驳方式的利弊,在具体工程中根据自己的特点和使用条件选用不同的形式,完善了"桥-建结合车站"中车站主体与区间桥梁接驳方式概括和总结,并为以后的实际工程起到指导的作用。

Discussion of the Accession Mode of Unified Structure Station and Interval Bridge in Urban Rail Transit

Systematic investigation and analysis of the ac-cess modes of unified bridge-building and interval bridge were carried out in this paper. The existing could be divided into two types： ①setting corbel in the side span beam （ bridge station ） or in the frame beam （ frame station） . ②setting double column within side span to separate interval box beam or U shape beam and station structures Based on mechanic character and equip-ment function of station building, the advantage and disadvan-tage of two access mode was discussed, In the selection of spe-cific projects in choosing different forms according to individual characteristics and service conditions in specific engineering. The improving summary and conclusion of access modes of uni-fied bridge-building and interval bridge could provide guideline in practical project.
