不同运行模式下的市域轨道交通最小曲线半径研究

市域轨道交通在我国尚处于起步阶段,实际工程运用较少,国内各种规范均不适用,对市域轨道交通线路最小曲线半径进行研究具有重要意义。在传统的线路设计参数计算方法的基础上,基于不同的运营模式和乘坐模式,分不同速度匹配模型进行研究,并通过与其他常规轨道交通制式进行对比,结合舒适度分析,对市域轨道交通的计算结果进行优化改正,给出不同速度下线路最小曲线半径的建议值。

Research on Minimum Curve Radius of Urban Rail Transit in Different Operating Modes

In view of the fact that the domestic urban rapid rail transit is still in its infancy with few practical engineering application and none of the available norms are applicable,the research on the minimum curve radius of urban rail transit lines is of great significance. Based on the traditional circuit design parameter calculation method,the paper conducts the modeling of different operating and riding modes in terms of different speeds,and optimizes the calculation results of urban rail transit by means of comparison with other conventional rail transit systems and riding comfort analysis. The minimum curve radiuses for lines under different speeds are recommended.
