轨道综合作业对高速铁路有砟轨道几何不平顺改善效果
|
摘要
根据高速铁路有砟轨道综合作业前后的轨道几何状态检测数据,分析了以大机作业、人工精调和钢轨打磨为主的综合作业对高速铁路有砟轨道几何不平顺的改善情况。分析结果表明:大机作业、人工精调和钢轨打磨的综合作业可联合改善轨道几何不平顺,其中,大机作业对高低、水平、三角坑不平顺的改善率分别为20.95%、12.90%和13.16%,人工精调对高低、水平、三角坑和轨距不平顺的改善率分别为11.97%、5.56%、7.43%和6.12%,钢轨打磨对高低和轨向不平顺的改善率分别为4.85%和3.88%,轨道质量指数在大机作业、人工精调、钢轨打磨后的改善率分别为11.54%、6.91%和1.10%,因此,大机作业和人工精调对各个单项不平顺改善效果明显,大机作业的贡献最大,而人工精调可在一定程度上改善轨距不平顺,钢轨打磨对高低不平顺和轨向不平顺进一步改善,但对水平不平顺、轨距不平顺和三角坑不平顺等改善效果不明显;经过综合作业,单项不平顺与轨道质量指数均呈下降趋势,其中轨道质量指数、高低不平顺、水平不平顺、右轨向不平顺近似呈幂函数趋势降低,左轨向不平顺近似呈线性函数趋势降低,三角坑不平顺近似呈对数函数趋势降低,反映了大机作业对轨道几何状态改善程度高,人工精调、钢轨打磨进一步改善部分单项不平顺的情况。
According to the track geometry inspection data captured before and after comprehensive maintenance of ballast track in a high-speed railway,the improvements in the geometric irregularity of comprehensive maintenance that consists of large machinery work,artificial fine adjustment,and rail grinding were analyzed.Analyses result shows that the large machinery work,artificial fine adjustment,and rail grinding can improve track geometric irregularity effectively.Among them,the improvement rates of large machinery work on track vertical,cross,and twist irregularities are 20.95%,12.90%,and 13.16%,respectively,the improvement rates of artificial fine adjustment on track vertical,cross,twist,and gaugeirregularities are 11.97%,5.56%,7.43%,and 6.12%,respectively,and the rail grinding can improve the track vertical and alignment irregularities by 4.85% and 3.88%,respectively.The track quality index(TQI)improves by 11.54%,6.91%,and 1.10%after large machinery work,artificial fine adjustment,and rail grinding,respectively.Large machinery work and artificial fine adjustment have obvious effects on the improvement of single irregularities.The contribution of large machinery work is the largest,whereas the artificial fine adjustment can improve the track gauge irregularity to a certain extent,and the rail grinding can further improve the track vertical irregularity and track alignment irregularity,but have no obvious effects on the track cross irregularity,track gauge irregularity,or track twist irregularity.Through the comprehensive maintenance,the single irregularity and TQI both decrease,in which the TQI,track vertical irregularity,track cross irregularity, and right track alignment irregularity decrease approximately as power functions,the left track alignment irregularity decreases approximately as a linear function,and the track twist irregularity decreases approximately as a logarithmic function.The geometrical state of the track irregularities improves effectively after large machinery work,and the artificial fine adjustment and rail grinding can further improve some single irregularities.
