摘要

摘要:
为保证捣固作业效果达到预期目标，需严格控制影响作业质量的不利因素，首先，以有砟轨道捣固作业数据为研究对象，分析影响作业质量的关键因素，探讨传统方法修正起道方案的基本原理；其次，将多因素约束条件纳入目标线形构造过程，并遵从历史作业规律，对起道量进行修正，构造一种用于提升轨道高低调整效果的起道方案综合修正方法；最后，以某高速铁路有砟轨道捣固作业为工程背景，验证综合修正方法的实施效果. 研究结果表明：在起道方案制定过程中施加针对性控制措施，有利于提高捣固作业对轨道不平顺的调整能力；捣固后，线形实测值与目标值之间决定系数高达0.92；方案起道量与实际起道量之间均方误差为1.8 mm；高低60 m中点弦测值降至4.0 mm，高低轨道质量指数降至0.28 mm.

Abstract:
In order to make the effect of tamping operation meet the expected goals, it is necessary to strictly control the unfavorable factors affecting the quality of the operation. Firstly, by taking the tamping operation data of ballasted track as the research object, the key factors affecting the operation quality were analyzed firstly, and the basic principles of the traditional methods to correct the lifting scheme were discussed. Secondly, by incorporating the multi-factor constraints into the target line construction process and correcting the lifting value according to the historical operation law, a comprehensive correction method of the lifting scheme for improving the adjustment effect of track height was constructed. Finally, by taking the ballasted track tamping operation of a high-speed railway as the engineering background, the implementation effect of the comprehensive correction method was verified. The results show that the application of targeted control measures in the process of lifting scheme formulation can improve the ability of the tamping operation to adjust the track irregularity. The coefficient of determination between the measured value and the target value of the alignment after tamping is as high as 0.92, and the mean square error between the planned lifting value and the actual lifting value is only 1.8 mm. The mid-chord value of 60 m is reduced to 4.0 mm, and the track quality index is reduced to 0.28 mm.
