通过对既有铁路曲线正矢和缓和曲线超高的重新合理布置,结合兰新铁路既有曲线正矢和缓和曲线超高布置方法进行比较,确定一种更加科学合理的既有铁路曲线正矢和缓和曲线超高的布置方法,以适应既有铁路提速后曲线维修养护的高标准、精益化。
Through the re-rational arrangement of curve positive vector and mild curve of existing railway and the comparison of the existing curve positive vector and the super-high-altitude arrangement method of Lan-Xin Railway, a more scientific and rational railway curve positive vector And to ease the ultra-high layout of the curve in order to adapt to the high standards and lean of the curve maintenance and repair after the acceleration of the existing railway.
