高速、城际铁路车站分布及通过能力研究

Study on Station Distribution and Passing Capacity of High Speed Railway and Intercity Railway

近年来,我国高速铁路、城际铁路快速发展,已运营的高铁、城际铁路的通过能力与设计能力存在较大的差距,尤其高铁成网后,车站分布与天窗设置方式及时间安排、列车追踪间隔、线路通过能力、列车开行方案等将成为一个系统性问题。采用铺画运行图与理论计算相结合的方法,利用扣除系数法和直接计算法,分别计算不同速度旅客列车共线运营条件下满足能力需求的合理站间距离,并以宝兰高铁、西成高铁为例,验证车站分布与通过能力的研究成果。

In recent years,China＇s high-speed railway and intercity railway are developed rapidly,and the passing capacities of the operating high speed railway and intercity railway fall behind their designed capacities. Since the establishment of the highspeed railway network, station distribution,setting of maintenance window and time arrangement, interval of trains, line capacity,and train operation schedule may become a systemic problem. In this paper,the method of combining the map and the theoretical calculation is used and the reasonable distance between stations is calculated by deducting coefficient method and direct calculation method to meet the demand of capacity under the condition of collinear operation of passenger trains of different speed. Based on Baoji-Lanzhou High Speed Railway and Xi＇an-Chengdu High Speed Railway,the research results of station distribution and passing capacity are verified.
