摘要
为实现京沈客运专线对京承高速公路与机场北高速互通区的跨越,京沈客运专线温榆河特大桥采用(109.8+170+170+90.8)m V撑连续梁结构体系。通过介绍温榆河特大桥V撑连续梁的工程概况及该箱梁与V撑构造特点、内力分析情况、预应力体系及钢束布设、动力分析的成果等,论证V撑连续梁方案的可行性,为高速铁路大跨结构的设计提供有益的参考。
To across over Beijing - Chengde expressway and the interchange area of Airport North expressway,a （ 109. 8 ＋ 170 ＋ 170＋90. 8） mV supporting continuous beam system is used in Wenyu River Bridge,a super large bridge located on Beijing - Shenyang dedicated passenger railway line. In this paper,the structural characteristics of the box girder and V support,the internal force analysis results, the prestressed system and dynamic analysis results are introduced, which provide references for the design of long-span structures of high-speed railway.
