摘要
针对我国既有线提速200 km/h设计现状情况,结合改建铁路胶济电气化工程设计经验,对既有线提速200 km/h的平纵断面设计思路及方法进行初步探讨,指出合理设计既有线提速200 km/h的平纵断面应从确定提速区段和速度目标值及最小曲线半径,线间距,坡度等方面入手。
Aiming at the situation for the speed-raising 200 km/h design of existing lines in China, the paper combining with the design experience for reconstruction railway of Qingdao-Ji＇ nan electrization project, has the primary exploration for the design ideas and methods for speed- raising 200 km/h plain vertical section of existing lines, and points out the reasonable design for the speed-raising 200 km/h plain vertical section of existing lines should be started from the targeted value of the speed in the speed-raising section, the minimum curve radius, the line space and the slopes etc..
