Self-adaptive overall recovery method for existing railway line plane

According to the self-adaptive overall recovery method for the existing railway line plane, self-adaptive segmentation and dynamic self-adaptive recovery are carried out on different line shapes mainly including straight lines and curves, the self-adaptive thought that different methods are adopted for different line shapes is proposed for the first time, the method can be suitable for various existing railway line shapes, and the overall recovery efficiency of the existing railway line plane is improved. And a self-adaptive overall recovery method is obtained through section fitting and optimization fitting. The self-adaptive overall recovery method provided by the invention has the characteristics of good optimization effect, low calculation difficulty and high convergence speed, and can be well applied to recovery application of the railway line plane. 本发明提供了一种既有铁路线路平面的自适应整体恢复方法，对以直线为主、以曲线为主的不同线形，进行自适应分段及动态自适应恢复，首次提出了针对不同线形采用不同方法的自适应思想，可以适用各种既有铁路线形，并通过区段拟合以及优化拟合得到了自适应整体恢复方法。本发明提供的自适应整体恢复方法具有优化效果好、计算难度小且收敛速
