摘要
郑州至济南高速铁路是我国“八纵八横”高铁网中主通道的区域连接线,为河南省“米”字形高速铁路网的重要组成部分。根据该线的功能定位及项目特点,结合城市规划、环保以及工程经济等方面,分析确定合理的郑州枢纽引入、线路走向以及黄河桥位方案。在创新技术方面,4个创新技术国内首次运用,郑州万滩黄河公铁大桥大跨度无砟轨道钢梁、跨度40 m预应力混凝土简支箱梁整孔预制架设,郑州枢纽既有运营高铁插铺道岔以及新乡东站既有高铁站并站路基等工程中开展了多项科研工作,实现了技术创新突破,为我国高速铁路的发展积累了宝贵的技术经验。从总体设计角度出发,重点介绍郑济高铁的设计特点和创新点。
Zhengzhou-Ji’nan High-speed Railway is the regional connecting line of the main channel in the National High-speed Railway Networks.It is an important part of the“star-type” high-speed railway network in Henan Province.Combined with urban planning,environmental protection and engineering economy,a reasonable scheme for entry into Zhengzhou hub,the route of the railway and the location of the Yellow River bridge are determined according to the functional orientation and project characteristics of the line.In terms of innovative technologies,four innovative technologies have been applied for the first time in China.Scientific researches have been carried out on the large-span ballastless track steel beam on Zhengzhou-Wantan Yellow River Highway and Railway Co-construction Bridge,the erection technology of precast 40 m simply-supported box beams,the existing operating high-speed railway plug-in turnout of Zhengzhou hub and the subgrade of the existing high-speed railway station of Xinxiang East Station,which has achieved technological innovation breakthroughs and accumulated valuable technical experiences for the development of China’s high-speed railway.From the perspective of overall design,this paper focuses on the design features and innovations of Zhengzhou-Ji’nan High-speed Railway.
