摘　　要：以高速铁路曲线整正作业时的正矢作为研究对象,通过分析实测正矢偏差的组成,建立了一种优化线形与设计线形间的正矢偏差模型,并以轨道实测正矢平顺性判定结果不变(不超限)为条件,提出了一种平面曲线特征点偏移接受域(即所允许的特征点最大偏移量)算法。该算法为评价特征点辨识精度是否合适以及判断线路的变形是否会对整体平顺性的判定结果造成影响,进而决定是否以优化线形代替设计线形对实测线路进行整正作业提供了理论依据。该算法可以移植应用到普速、快速线路中。Taking the versine of high speed railway curve adjustment operation as the research object,a versine deviation model between optimal alignment and design alignment was established by analyzing the constitution of measured versine deviation.A newalgorithm for plane curve feature point offset acceptance region,which was the allowed maximum offset of the feature point,was proposed in the condition of invariant judgment result（no exceeding） for the measured track versine regularity.This algorithm provides a theoretical basis for evaluating the suitability for feature point identification accuracy and the influence of the track distortion on judgment result of the whole track regularity for deciding to whether implement the adjustment for actual railway track by replacing design alignment with optimal alignment or not,which could be applied to the normal speed railways and fast railways.
