摘要
遂渝铁路是我国第一条新建时速200 km铁路,跨越涪江和嘉陵江时采用大跨度预应力混凝土连续刚构桥。在已建成的铁路桥梁中,无论是设计行车速度、大跨桥上无缝线路设计,还是结构形式均有新的突破。介绍其结构设计,并着重对其关键技术分析进行论述。
The Suining Chongqing Railway is the first newly-built railway with running speed 200 km/h in China and long span prestressed concrete （PC） continuous rigid-frame bridges have been built for the railway when it stretches across the Fujiang River and Jialingjiang River. Among the railway bridges having been completed, the bridges on the newly built railway have new breakthrough in aspect of their design running speed, design of jointless tracks for long span bridges and structural forms. In this paper, the structural design of the bridges on the new railway, particularly the analysis of the key techniques thereof, is mainly described.
