京沈客运专线引入沈阳铁路枢纽桥梁方案研究

Research on Bridge Options for Integration of Beijing-Shenyang Dedicated Passenger Railway into Shenyang Railway Junction

京沈客运专线引入沈阳铁路枢纽工程跨越秦沈客运专线和多条普速铁路、河流、市政道路等,特殊结构桥梁多。在时间空间均受限的条件下,通过对丁香湖疏解区和大成站疏解区"穿针引线"的桥梁方案研究,保证工程的顺利实施;通过结构形式研究,保证施工时的既有线运营安全并减少对城市基础设施的干扰。对桥梁方案因地制宜的尝试和永临结合的设计,为高速铁路引入枢纽的线形优化创造条件,节约城市用地,使铁路建设与城市规划更加融合,实现投资节约化,施工标准化,运营安全化,养护便捷化。

The Beijing - Shenyang dedicated passenger railway integrated into Shenyang railway junction crosses Qin - Shen dedicated passenger railway and several normal speed railways, rivers, municipal roads with many special structure bridges. Under limited conditions for time and space, the researches on the bridge scheme of the Clove Lakes region and the Dacheng station area ensures the smooth implementation of the project. Through the study of structures, the operational safety of existing lines during the construction is guaranteed and the impact on urban infrastructure is reduced. The attempt to solve local problems in view of local conditions and the combined design of temperate and permanent projects helps the optimization of high-speed railway alignment into the railway junction, which, in turn, saves urban land and harmonizes the railway construction with urban planning and fulfills investment reduction, construction standardization, safe operation and easy and quick maintenance.
