摘要
铁路曲线整正,就是把已变形的不规则曲线中线,拨正到接近于既有线路平面的正确位置,并以此作为进一步改建既有线和增建第二线的设计依据。目前,既有铁路曲线整正方法主要是绳正法,针对它存在的问题,提出了改进后的计算方法,并对原有的部分计算公式进行了优化,通过软件来实现数据的计算和处理,实现了铁路既有线的计算仿真设计。
Rectification for railway curve, a method is needed to put the anamorphic rail back to where it has been designed to be. At present, a traditional way called the rope-rectification method is mainly used to rectify the existing line. In this article the problem in the rope-rectification method has pointed out. In order to solve the problem, there is a better way to rectify the anamorphic rail, which is called the new method. It is on the part of the original formula has been optimized through the software program to achieve the computing and data processing, to achieve both the railway line simulation of the design.
