高速铁路引入既有铁路地区方案及联络线设置研究

Schemes of High-speed Railways Leading into Existing Railway Hub and Railway Connection Setting

随着我国高速铁路网的发展与完善,新建高速铁路引入既有铁路地区的情况逐渐增多,考虑既有设施、客站布局、运营管理、城市规划、工程投资等因素,对引入既有站方案和新建站方案进行归纳整理,并结合具体案例分析不同方案的优缺点及适用条件。基于跨线列车运输需求,研究联络线设置的必要性、设置条件及优缺点,对不同联络线方案进行综合比选。针对既有铁路未预留接口、无砟轨道改建困难、路基帮宽导致的沉降等问题,结合漯河西站京广高铁场实例,确定联络线引入对应的车站改建方案。

With the development and improvement of China’s high-speed railway network,the situation that new high-speed railways lead into existing railway hubs is gradually increasing.Considering the existing facilities,passenger station layout,operation management,urban planning,engineering investment and other factors,the schemes of leading into existing stations and building new stations are summarized.The advantages,disadvantages and applicable conditions of different schemes are analyzed combined with specific cases.Based on the demand of cross-line train,the necessity,setting conditions,advantages and disadvantages of railway connection setting are studied,and different railway connection setting schemes are comprehensively compared and selected.In view of the problems such as no reserved interface of the existing railway,difficult reconstruction of ballastless track and settlement caused by subgrade widening,combined with the example of Luohe west railway station in Beijing-Guangzhou high-speed railway,the station reconstruction scheme for railway connecting introduction is determined.
