徐宿淮盐通铁路速度目标值研究

Research on Speed Target Value of Xu Su Huai Yan Tong Railway

速度目标值是铁路主要技术标准的核心,其内涵决定了基础设施、设备及各项配套设施标准的选择,直接影响到工程设备投资、客流量以及运营模式等,并关系铁路在区域内客运市场的竞争力,因此如何科学、合理、经济的确定速度目标值,是铁路项目设计的重点。文章根据徐宿淮盐通铁路的等级,提出250 km/h、300 km/h和350 km/h 3种速度目标值方案,通过对其客流特点和相关规划的研究,确定该线合理的时间目标值,并通过旅客时间价值分析、相邻路网速度匹配、站间距与经济据点分布、主要技术标准分析、工程经济比较、财务分析比较等因素的综合比选,推荐徐宿淮盐通铁路选择250 km/h的速度目标值方案。

Speed target value is the core of main technical standards of railway,which determines the selection of infrastructure,equipments and various facilities standards. It directly affects the investment of engineering equipment,passenger flow and operation mode,and also affects the competitiveness of railway passenger transport market in the region. So how to determine the speed target value scientifically,reasonably and economically is the key point of railway project design. According to the classification of Xu Su Huai Yan Tong railway,this paper proposes three speed target value schemes with the speed of 250 km / h,300 km / h and 350 km / h. Through the study of passenger flow characteristics and related planning,the reasonable time target value of the line is determined. And through the analysis of the time value of passengers,speed matching of adjacent road networks,distribution of station spacing and economic stronghold,main technical standards,comparison of engineering economy and comparison of financial analysis,it draws a conclusion that 250 km / h speed target value scheme is recommended.
