上跨繁忙干线铁路限界处简支槽型梁施工技术

Construction Technology of Simply Supported Groove Beam at Upper Limit of Busy Main Line Railway

随着经济发展,城市扩张和铁路网建设的迅猛发展,目前国内上跨既有营业线铁路的各种桥梁施工非常多。在繁忙干线铁路建筑限界处施工简支槽形梁,采用传统的施工技术组织施工就非常困难,针对成功实施案例进行细述,为同类施工提供借鉴。

With the rapid development of economic development,urban expansion and railway network construction,there are many constructions of various bridges on the existing railway lines in China. It is very difficult to construct simple-supported troughshaped beams at the boundary of busy main railway construction. It is very difficult to organize construction by traditional construction techniques.This paper describes the successful implementation cases and provides reference for similar construction.
