摘　　要：城市轨道交通工程中暗挖隧道的爆破作业是极其重要的施工工序,特别是对近接建筑物的安全影响及防护技术,是行业持续关注的热点和难点问题。以贵阳市轨道交通S1线黄河北路站~望城坡站区间暗挖隧道工程采用“单孔单响错相爆破减震施工技术”有效降低爆破振动值为依托,从施工工艺流程、爆破方案设计两方面着手,重点分析了爆破参数计算、延时参数数据及爆破后振动数据分析,研究成果可作为建筑物保护案例的有益补充,为类似工程提供参考,也可促进贵阳市轨道交通工程的安全有序施工。The blasting operation of underground tunnel in urban rail transit engineering is an extremely important construction process,especially the safety impact and protection technology of adjacent buildings,which is a hot and difficult problem that the industry continues to pay attention to.The underground tunnel project between Huanghe North Road station and Wangchengpo Station of Guiyang rail transit line S1 is adopted the"puckering"single ring blasting vibration fault phase construction technology as the backing,effectively reduce the blasting vibration value from two aspects:the construction technological process,the design of blasting scheme,blasting parameter calculation,time delay parameters are emphatically analyzed data and after the blasting vibration data analysis,The research results can be used as a useful supplement for building protection cases,provide reference for similar projects,and promote the safe and orderly construction of Guiyang rail transit project.
