摘要:

针对扣除系数法在高速铁路通过能力计算上存在的问题,对其适应性进行分析.从需求的角度分析高速铁路通过能力与既有线的差异,明确了高速铁路通过能力的概念.分析扣除系数法的思想本质并从3 个基本假设入手分析其思想本质上的适应性.对扣除系数法相关研究进行总结,并提炼出其方法本质即时间占用的重叠关系,归纳出了4 种基本情况,采用算例对其方法本质进行验证,结合高速铁路特点,对其方法本质存在的3 个问题进行概括.研究证明了原有的扣除系数法已不适应我国高速铁路通过能力的计算,并在最后给出了进一步研究高速铁路通过能力计算方法的相关建议.

Abstract:

Based on the problem of removal coefficient method in calculation method of high- speed railway’s passing capability, the adaptability is analyze. We study the differences between high- speed railway and existing lines, and identify the concept of high-speed railway’s passing capability. We research the thought essence and research on the adaptability based on the three basic assumptions. The development trends of the method are summarized and the essence of technology is refined as overlap relation of time occupied. An example shows the feasibility and effectiveness of the proposed method. We summarize three problems of technology essence with the characteristics of high-speed railway. The results indicate that the removal coefficient method cannot adapt with the calculation of high-speed railway’s passing capability, and a possible direction for future research is put forward.

Key words: railway transportation, passing capability, removal coefficient method, thought essence, technology essence, adaptability analyze
