摘要
介绍了无碴轨道道床竖曲线弦测法施工精度控制要点,即控制体系的设计,弦线点的设置,矢矩的合格范围以及轨排铺设和弦线量测的控制要点。详细阐述了弦线矢矩处理程序和注意事项。
The construction precision control point of chord surveying method for ballastless track ballast bed is introduced, including design of control system ,layout of chord point, rational range of circle distance, control point of laying track and chord surveying. Treatment process of chord distance and points for attention are expatiated in detail.
