紧邻既有地铁线的隧道爆破施工探讨

Discussion on Blasting Operation near Metro Line

介绍紧邻正在运行的地铁线泵房爆破施工的有害效应控制方法。根据不同距离,采用不同爆破方法,分区爆破。泵房一侧采用密打孔、小药量和不耦合装药;采取超前导洞加探孔的方法。同时,完善相应监测手段,实时掌握爆破振动和结构变形数据,将信息快速反馈给施工和相关人员,使工程顺利完成。

This paper introduces the harmful effect control method of pump house blasting operation near a Metro line. Different blasting methods are adopted according to different distances. Zonal blasting method is also used. And on the side of the pump house, blasting skills including close holes, small charge and non coupling charge are introduced. Monitoring measures are improved, and real-time blasting vibration and structural deformation data are timely returned for the completion of the project.
