结合沈丹客运专线,对车站两端曲线超高进行设计分析,根据实际的运营工况和列车运行速度—走行距离曲线(V-S曲线),通过理论公式计算得出曲线设计超高值,并对其进行安全性和舒适度检算。为了得到合理的曲线超高值,对超高值进行反复调整优化,尽可能减小未被平衡的欠超高和过超高,这既能保证旅客的舒适度,又可保持两股钢轨受力比较均匀,从而达到设计要求。 Combined with Shen-Dan Passenger Dedicated Line, design and analysis of the ultra-high curve at both ends of the station are carried out. According to the actual operating conditions and the train running speed-distance curve (VS curve), the curve design ultra-high value is obtained through theoretical formula It conducts security and comfort calculations. In order to get a reasonable curve of ultra-high value, the super-high value repeatedly adjusted to optimize, as far as possible to reduce the unbalanced under the ultra-high and ultra-high, which can ensure passenger comfort, but also to maintain two rails The force is more uniform, so as to meet the design requirements.
