市域快速铁路蓟县至大港段规划建设技术标准研究

Research on Technical Standards for Planning and Construction of Urban Express Railway from Jixian to Dagang

天津是全国综合性交通枢纽,市域南北交通网络布局较为薄弱。随着天津市城市化进程不断加快,带动区域经济发展加速,迫切需要加快南北交通布局及建设;参照北京、上海等国际化大都市的市域快速铁路的发展模式,结合天津市的轨道交通、城际网的规划以及本线自身的特点,初步总结出了市域快速铁路的规划建设标准为设计速度200 km/h的双线城际铁路。

Tianjin is a national comprehensive transportation hub, and the city＇s transportation in north-south direction is insufficient. Along with the rapid development of Tianjin urbanization to accelerate and promote regional economy, it is urgently needed to speed up the construction of the north-south traffic. With reference to the development of express railways of Beijing and Shanghai, and in view of the planning of the rail transit and inter-city network of Tianjin, and the local conditions of the line from Jixian to Dagang, it is suggested initially to build a double-line inter-city express railway at the designed speed of 200 km/h.
