接轨方案选择是铁路选线设计工作的重要组成部分,主要包括接轨点和接轨方向选择。前者解决设计线在既有线哪个车站接轨的问题;后者解决在该站哪一端接轨的问题。接轨点选择不但影响设计线的局部走向,而且影响设计线的客货运程、运输效率、工程投资和运营支出。接轨方向的选择影响主要客货流方向是否顺直,是否存在折角运输,影响运输效率;并且影响城市规划与拆迁工程的大小。通过一些实例,分析影响接轨方案选择的主要因素,及如何对各种因素进行全面分析,选择经济合理的接轨方案。
The choice of connecting plan is an important part of the design of railway route selection, including the choice of connecting point and connecting direction. The former solves the design line which station in the existing line with the problem of convergence; the latter to solve the problem of which end of the station to meet the rail. The choice of connecting points will not only affect the local trend of the design line, but also affect the design line of passenger and freight transport, transport efficiency, project investment and operating expenses. The choice of the direction of convergence affects the direction of the main passenger and freight flow is straight, whether there is folding corner transport, affecting transport efficiency; and the size of urban planning and demolition projects. Through some examples, it analyzes the main factors that influence the choice of the connecting plan and how to make a comprehensive analysis of the various factors and select the economical and reasonable plan of joining together.
