铁路线间距不等的并行段Ⅰ型双块式无砟轨道轨排精调的实现

摘要

通过轨检小车进行无砟轨道轨排静态平顺性调整即轨排精调，需具备两个条件，即 CPⅢ控制点的测量以及线形设计文件的编制。铁路并行段设计上通常只提供基准线的平、纵曲线要素，第二线平面上通过线间距控制；里程及高程则通过投影实现。基于安伯格 GRPwin 程序，通过设计文件的不同组合可实现铁路并行区段且线间距不等情况下的线形投影。%To conduct static smoothness adjustment of ballastless track with inspection trolley,i.e.fine adjustment of track,two elements are required,namely measurements of CPIII control point and preparation of linear design documents. Railway parallel section design usually only provides horizontal and vertical curve elements of the baseline,and the second line plane iscontrolled with line spacing,while the mileage and elevation are realized through projection.Based on Amberg-GRPwin program,linear projection of parallel railway section with unequal line spacing can be realized with different combi-nations of design documents.
