| 摘 要： | 传统铁路曲线施工放样经常使用切线支距法、偏角法,而拨正曲线经常使用"绳正法",这些曲线施工放样和拨正曲线的方法在施测过程中曲线长度通常不为10m的整数倍,这种现象给放样、拨正带来了不少的弊端.本文以成昆线铁路在改扩建过程中把曲线长度调整为10m的整数倍为例,说明了把曲线长度设计成10m整数倍后,使铁路曲线的现场放样操作更为简化,拨正更为快速、方便,保证了线路曲线的圆顺度.

| Abstract: | The method of tangent offset and deflection angle method are frequently used for curve lofting in the traditional railroad construction while "rectification approach" is employed to correct the curvature of a curve.However,the curve length is usually not the integral multiple of l0 meters when the curve lofting and smoothness correction are conducted using the methods stated above in a construction.This kind of phenomenon for lofting and smoothness correction brings many malpractices.In this article,the aut... |
