摘　　要：轨道的高平顺性是确保高速列车平稳、安全运行的关键。目前,轨道不平顺状态调整方案制定的主要方式是采用随机软件,以人工手动调整为主,依据剩余偏差反馈的轨道平顺性效果修正调整方案。该方式不仅费时费力,且受人为因素影响,难以获取客观最优的精调方案。提出无砟轨道高平顺多约束自适应迭代优化方法,以预设长度的钢轨分段为基本单元,逐点滑动分段区间求解待调整钢轨的扣件优化调整量,并基于整体轨道不平顺评价迭代修正约束界值,根据迭代终止判定和最佳次数判定条件获取全局最优的钢轨扣件调整量。该方法可高效、准确、自动化实现复杂约束条件下轨道高平顺及其最优调整量的双重目标,解决轨道几何状态调整方案制定费时费力、调整效果参差不齐的问题,研究成果可对高速铁路轨道竣工测量和运维服务提供参考。High regularity of track is crucial for ensuring high-speed,stable,and safe train operation.Currently,the primary method for formulating an adjustment solution for track irregularities is to use the supporting adjustment software of a trolley,mainly based on the manual mode,with the correction being made according to the track regularities calculated by the residual deviations of track inspection points.Greatly affected by human factors,the adjustment process is not only inefficient,time-consuming,and laborious,but also difficult to obtain an objective and optimal adjustment solution.Therefore,this paper proposed a multi-constraint adaptive iterative optimization method for the high regularity of ballastless tracks.Taking the rail segment of preset length as the basic unit,this method calculated the optimal adjustment values of rail fasteners in the basic unit by sliding the segmented window point by point.Based on the overall track irregularity evaluation,the method can iteratively correct the constraint boundary values.According to the iteration termination judgment and the optimal number of judgment conditions,this method can calculate the optimal adjustment value of the rail fasteners in the global optimal track state.The experimental results show that this proposed method can efficiently,accurately,and automatically achieve the dual objectives of high regularity and corresponding optimal adjustment values under complex constraints,solving the problems of time-consuming and laborious formulation of the track adjustment solution,and inconsistent adjustment results.The research results may provide reference for the track completion survey and the operation and maintenance services of high-speed railways.
