英德硫铁矿露天窄轨运输线路,在大修和维修中常常遇到平面曲线的整正问题。采用正矢法整正平面曲线,是常用的方法。本文仅就这方面的问题进行讨论。 (一)采用正矢法整正铁路平面曲线的方法 露天矿山窄轨铁路在采用正矢法整正平面曲线时,往往整正后的曲线中心线与采用偏角法所施测的曲线中心线不相符合,而且曲线越长差距越大(指相同半径的曲线),产生这种现象的原因是:
Anglo-German pyrite open-air narrow-gauge transport lines, overhaul and maintenance often encounter the problem of rectification of the planar curve. The use of positive vector method to correct the plane curve is the commonly used method. This article only discusses the issues in this area. (A) the use of positive vector method to correct the plane curve of the railway Open-pit mine narrow-gauge railway in the use of positive normal rectification of the plane curve, the curve is often after the correction of the center line and curve method using the curve centerline Do not match, and the longer the curve the greater the gap (referring to the same radius of the curve), the reason for this phenomenon are:
