Abstract In accordance with the rock blasting proceeded on high steep slope of electrified double track railway line with a distance of 4m between the centers of tracks,and combined with the most difficult work site of the Zhu-Liu electrified double track railway,five kinds of construction methods applied at work site are introduced emphatically,including the selection of adaptive blasting parameters and the distribution of blasting holes,as well as the safety check and calculation for vibration and shock wave of blasting. And therefore，the safety，high efficiency and economical results are obtained in construction works.
