潍坊至宿迁高铁引入新沂(宿迁)地区方案研究

Scheme Study on the Introduction of Weifang-Suqian High-Speed Railway to Xinyi(Suqian)Railway Area

京沪二通道是中长期铁路网规划缓解京沪主通道能力的辅助通道,目前京沪二通道潍坊以北、宿迁以南段线路均已建成或在建,仅潍坊至宿迁段线路尚处于前期研究阶段。新沂(宿迁)地区规划引入多条规划线路,各线建设时机不一致,本线引入地区时,需统筹考虑地区内经济据点分布、路网灵活性、工程投资等,提出合理的地区引入方案。并提出结论:(1)线路引入地区时,应充分考虑各线的建设时机,合理构建跨线联络线,既可以增强路网灵活性,又可以节省工程投资;(2)随着时代发展,铁路路网规划会动态调整,近期工程实施时,应充分研究规划线路可能的引入方案,同时预留后续路网优化条件。

The Beijing-Shanghai Second Channel is an auxiliary channel for the middle and long-term railway network planning to alleviate the capacity of the Beijing-Shanghai main channel.At present,the lines in the north of Weifang and the south of Suqian have been built or are under construction,only the line from Weifang to Suqian is still in the early stage of research.The Xinyi(Suqian)Railway area is planning to introduce several planned lines,and the construction timing of each line is not consistent.When the line is introduced into the area,it is necessary to take into account the distribution of economic strongholds in the area,the flexibility of the road network,and the investment of the project,and put forward a reasonable introduction scheme.It is concluded that:(1)when the line is introduced into the area,the construction timing of each line should be fully considered,and the cross-connecting line should be constructed reasonably,which can not only enhance the flexibility of the road network,but also save the investment of the project;(2)with the development of the times,the railway network planning will be adjusted dynamically.When the recent project is implemented,the possible introduction scheme of the planned line should be fully studied,and the conditions for the subsequent optimization of the road network should be reserved.
