| 摘 要： | 宁启线增建二线跨越新建沪通铁路时因纵断面受限,采用64m简支槽形梁-拱组合的大跨、低高度新型桥式,有效地解决了立交跨越问题。文章通过对该结构与其他桥式进行综合比较,阐述采用简支槽形梁-拱组合桥式的可行性、经济性及优越性,为类似工点提供设计借鉴。

| Abstract: | Due to vertical section limit for the second new line of the Ningqi line construction when across the newly built Shanghai — Nantong Railway, the new type bridge of 64 m simply supported channel girder – arch composite combining long span and low height is in use, having solved the problem of overpass diffi culty effectively. Through comprehensive comparison of the structure with other bridges, the paper elaborates the feasibility, economics and advantages of use of simply supported channel girder – arch composite bridge, providing design reference for similar work sites. |
