摘要
针对线间距为4m的电气化复线在高陡边坡上进行的石方爆破，结合株六电气化复线最难的爆破工点，重点介绍了施工中采用的五种施工方法和适用地质、孔网参数的选取，以及爆破振动和冲击波的安全检算，在施工中达到了安全、高效、经济的目的。
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 construc tion works.
