摘要
城际铁路到发线有效长度影响工程经济及运营效率等多个方面,依托深圳市城际铁路大部分采用地下敷设的工程背景,首先,分析城际铁路车站到发线有效长度优化的必要性,在解读到发线有效长度的相关规范后,深入分析到发线有效长度组成部分;其次,以新建深圳—惠州城际铁路项目为例,对城际铁路到发线有效长度的各组成部分进行调整,分别针对单方向和双方向开行列车的运营组织模式提出调整方案,提出合理化建议,并从运营组织、土建方案、控车影响、优化效果等方面对2个方案进行可行性分析。最后,推荐深圳市城际铁路采用双方向运行的模式,到发线有效长度可由400 m优化至355 m,有效控制项目建设投资。
The effective length of the receiving-departure track of the intercity railway affects engineering economy and operational efficiency.Relying on the engineering background that most of the Shenzhen intercity railways use underground laying,the necessity of optimizing the effective length of the arrival and departure lines of the intercity railway station is first analyzed.After interpreting the relevant specifications of the effective length of the hairline,in-depth analysis of the components of the effective length of the hairline.Secondly,taking the new Shenzhen-Huizhou intercity railway project as an example,the components of the effective length of the arrival and departure lines of the intercity railway were adjusted,respectively,for the operation organization of trains running in one direction and two directions.Adjustment schemes are proposed and reasonable suggestions are put forward.Feasibility analysis of the two schemes are done from the aspects of operation organization,civil engineering scheme,vehicle control influence,and optimization effect.Finally,it is recommended that the Shenzhen Intercity Railway adopts a two-way operation mode,and the effective length of the arrival and departure line can be optimized from 400 m to 360 m,effectively controlling the project construction investment.
