Applied Analysis and Study of Plane Design Standard for High-speed Railway

研究目的:线路平面设计标准决定了列车运行速度及舒适度水平,并影响项目建设的成本。通过对列车开行方案及V-S曲线分析研究,实现科学合理地选择平面设计标准,使其满足速度目标值、舒适度水平、沿线控制物的要求,实现线路方案技术经济合理、综合效益最优。研究结论:在有特殊技术要求和控制因素的地段,线路平面设计标准应根据建设项目的运营工况及V-S曲线研究确定。对于区间线路,应根据运营工况及V-S曲线,分析跨线列车与高速列车运营速差关系,研究确定合理的舒适度水平及相应的超高值,据此选择合理的平面设计标准;对于车站两端线路,还应分析曲线与站中心的距离关系及进出站列车与高速列车的速差关系,确定合理的舒适度水平及相应的超高值,据此选择相匹配的平面设计标准。

Research purposes： The plane design standard for railway line decides the train running speed and the comfortable level, and affects the construction cost. By analyzing and researching the train operating plan and the V - S curve, the scientific and reasonable plane design standard for the railway line is obtained in order to meet the design requirements for the speed target value and the comfortable level of train and controls along the railway line, and achieve the goal of obtaining the optimal railway line plan in technology and benefits. Research conclusions：For the section with the special technical requirements and control sector, the plane design standard for the railway line should be decided in accordance with the operation situation of construction project and researched result of V - S curve. For the sectional track, the plane design standard should be reasonably selected after analyzing the relation of the speed difference between the cross - line train and high - speed train and deciding the reasonable comfortable level of train and relative super - elevation of track in accordance with the operation situation of construction project and researched result of V - S curve. For the tracks on both ends of station, the plane design standard should be selected after analyzing the relation of the distance between the curve and the center of the station and the relation of the speed difference between the entering and departing trains and high - speed train, and deciding the comfortable level of train and the super- elevation.
