摘要
到发线有效长度是铁路工程建设项目的一项重要技术标准,关系到车站的设计规模和工程投资。针对公交化运营城际铁路的需求特点,研究采用CTCS-2列控系统条件下的城际铁路到发线有效长度优化方案。分析城际铁路到发线有效长度计算原理和影响因素,在保障行车安全、设计规范允许的前提下,优化各项计算参数,提出到发线有效长度优化为380m,360m,315m等3种不同使用功能的方案,从运营组织、控车影响等方面分析到发线有效长度优化方案的可行性。最后,推荐城际铁路到发线有效长度优化至360m的方案并分析了优化效果。
The effective length of arrival-departure track is an important technical standard in railway engineering projects and it is related to the design scale of stations and civil engineering investment. According to the demand characteristics of intercity railways operated by public transport, the optimization scheme for the effective length of arrival-departure track under the CTCS-2 train control system was studied. This paper analyzed the calculation principle and influencing factors behind the effective length of arrival-departure track on intercity railways and proposed three schemes with different functions after the effecitive lengths of arrival-departure track were optimized to 380 m, 360 m, and 315 m, respectively. The feasibility of the optimization schemes for the effective length of arrival-departure track was discussed from the two aspects of operation organization and vehicle control influence. Finally, the scheme of optimizing the effective length of arrival-departure track to 360 m was recommended and the optimization effect was assessed.
