摘　　要：根据线路中线的特点,介绍了线路平面缓和曲线和线路中线在曲线地段侧移的计算和处理方法。重点论述了曲线平移的计算公式推导,并提出了一种新计算方法。On basis of the features of the center line of the railway alignment, the author describes the methods of calculation and treatment of the lateral movement of the adjustment curves and the center line of the railway alignment at curved section, placing emphasis on the derivation of the calculation formula of the transition of the curves. The author also provides a new calculation method.
