云桂铁路是云南经广西至珠江三角洲的快速、大能力铁路通道,其列车速度目标值的选择应充分考虑沿线工程地质特征和相邻路网的技术标准。根据云桂铁路功能定位,从客货流构成特点、不同运输方式旅行时间比较角度分析,建议时间目标值控制在5 h以内。通过3个速度目标值方案的比选,以及速度目标值的适应性分析,推荐云桂铁路采用200 km/h预留250 km/h基础条件的列车速度目标值方案。
Yunnan-Guiyang Railway is a fast and large-capacity railway route from Yunnan to the Pearl River Delta via Yunnan. The selection of the target speed for the train should take full account of the engineering geological features along the line and the technical standards of adjacent roads. According to the functional positioning of Yun-Gui Railway, from the point of view of the characteristics of passenger and freight flow and the travel time of different modes of transportation, the proposed time target value is controlled within 5 hours. Through the comparison and selection of the three speed target schemes and the adaptability analysis of the speed target, it is recommended that Yun-Gui Railway adopt the train speed target value scheme of 200 km / h reserved for the basic condition of 250 km / h.
