摘要(Abstract)：

研究地铁隧道穿越十字路口和相邻燃气管线时,使用电子雷管的爆破方案及方法。利用电子雷管可以任意设置时间的特点,重点研究上、下台阶间及隧道间的最佳延时间隔时间。确定起爆的间隔时差,通过干扰错峰来达到减振的效果,使爆破振动对周围燃气管线的影响达到最小。
The blasting scheme and method using electronic detonators in subway tunnel crossed the intersection and the adjacent gas pipeline was studied.The characteristics of the electronic detonators time could be arbitrarily set was used.The optimal delay interval time between the upper and the lower bench and the tunnel were focused on.The initiation interval time was confirmed.The vibration reduction was achieved through interference peak,and the effect on surrounding gas pipelines from blasting vibration reached the minimum.
