随着高速铁路迅猛发展,车轮的冲击以及外界条件对铁路线路影响加大,从而使铁路线路与原设计的偏差较大,并且呈现一种不规律的现象。本文研究基于稳定估计的几何距离准则拟合线路参数的方法。用新拟合出的线路参数指导铁路线路养护作业,可使线路整正的工作量最小。
With the rapid development of high-speed railway, the impact of the wheel and the external conditions have an increasing impact on the railway line, resulting in large deviation of the railway line from the original design and an irregular phenomenon. This paper studies the method of fitting line parameters based on the geometric distance criterion of stable estimation. Using the newly fitted line parameters to guide the maintenance of railway lines can minimize the workload of line alignment.
