邻近建筑物的车站开挖爆破减振技术

Blasting Vibration Reduction Technique of Station Excavation with Adjacent Buildings

在车站明挖爆破施工过程中,为能保证爆破效果,同时减少爆破振动对邻近建筑物的危害,采用了沿基坑开挖边界打减振孔,并于仍然不能采用常规爆破的区域配合以数码雷管爆破等综合减振措施的爆破技术。有效的降低了爆破振动,确保了施工安全,可为类似工程提供一定的参考。

During the station open cut construction by blasting,in order to ensure the blasting efficiency,and reduce the harm to adjacent buildings from blasting vibration. The measures of excavating damping holes along the excavation boundary of the foundation pit,and setting digital electronic detonator in the area which couldn＇t use the conventional blasting were effectively reduce the blasting vibration and ensure construction security. It could provide certain reference for similar project.
