无砟轨道沉降评估中的关键技术研究

Study on Key Technology in Evaluation of BaUastless Track Settlement

以京沪高速铁路实测沉降观测数据为立足点，在对大量的数据统计分析研究的基础上，就无砟轨道沉降评估过程中的“异常数据判别及修正方法”与“小量级变形评估标准”两大关键技术开展系统研究，并提出一套解决办法，充实和完善了沉降评估体系，实践效果良好，并得到了大量推广应用。

Based on the measured settlement observation data of Beijing-Shanghai high-speed railway, through systematic research of a large amount of data, two key technologies, i.e. ＂ abnormal data determination and correction method＂ and＂ small grade deformation evaluation standard＂ are studied during ballastless track settlement evaluation. In addition, an effective solution is put forward to enrich and improve the settlement evaluation system, which receives good practical effect and is widely promoted and applied.
