| Abstract: | Stress dispersion of continuous welded rails is confronted with many difficulties,such as insufficient effective operation time,great influence on power supply and signal equipment,potential impact on next day’s operations and so on.This paper taking a project in Beijing as an example,stress dispersing of CWR is completed safely and efficiently by careful preparation,on-site visual division of labor and all-round professional guarantees.This paper introduces the stress dispersion and construction organization adjustment of CWR in the operation line of the urban mass transit,as well as the professional safeguard measures of power supply and signal system in detail. |
