高速铁路无砟轨道精测数据分析方法探讨

摘要

文章通过对国内现有高速铁路无砟轨道精测数据分析方法进行调查研究发现，目前主要存在数据分析不准及因素考虑不周全两方面问题，在研究论证基础上主要实现3个目标：科学统计分析、精准分析及综合全面分析。具体通过6条措施来实现：运用数理统计方法进行数据分析；解决现有DTS分析软件数据分析局限性的弊端；科学剔除异常数据；全面收集动静态检测数据；结合基础数据进行全面考虑分析；对现有方法不断修订、完善。以实际案例的形式进行验证、演示，成功建立了高速铁路无砟轨道精测数据分析方法。针对本方法进行了总结、归纳并提出4条改进建议。%Through the research on precise measurement data analysis methods for the existing high-speed railway ballast-less track so far, it is found that there are two problems:inaccurate data analysis exist and factors not considered com-prehensively, three goals shall be achieved on the basis of the research and demonstration:scientific and statistical anal-ysis, accurate analysis and comprehensive analysis which shall be achieved through six specific measures : the use of mathematical statistical methods for data analysis;solving the drawbacks of existing DTS analysis software data analysis limitations;scientificly removing the abnormal data;comprehensive collection of static and dynamic test data; compre-hensive consideration combined with basic data analysis;amending and improving the existing methods. Verification and demonstration shall be done in the form of actual cases, the precise measurement data analysis method for high-speed railway ballastless track is established. Finally, a summary and four suggestions for improvement are put forward for this method.
