摘要
复杂山区铁路大跨度预应力混凝土桥选用连续梁桥式还是连续刚构桥式,是方案设计时需考虑的首要问题。结合渝怀铁路具有代表性的几座桥梁设计,对桥式方案的比选,以及中跨与边跨合理的合龙顺序进行论述。
It is always the primary concern in the conceptual design to select the continuous girder bridge or the continuous rigid-frame bridge for a long-span and high-rise pier prestressed concrete (PC) railway bridge in the complicated mountainous region. With reference to the design of several typical bridges on Chongqing-Huaihua Railway, this paper describes and discusses the comparisons and selection of the structural types and the reasonable closure sequences for both side and main spans of the type of the bridge.
