| Above all, with the data acquired by tests.This thesis has analysized the lateral resistance , longitudinal resistance and rail creep etc between ballast and sleeper before and after mass machine work .Discussed the effect of mass machine on stability of continuously welded rail track, reseached the change regularity of fastening-down temperature of rail, which is resulted by mass machine work, and have settled the suitable range of work temperature which guarantees the stability of jointless railway .What's more .This thesis has put forward the appropriate work pattern, work temperature and work area for mass machine work in future. At attention in production of mass machine ,which can in return raise the work productiveness of mass machine . |
