【Abstract】 With a lot of measuring data in situ, the ground vibration caused by the blastingduring the subway test construction in Qingdao City is studied in this paper. The effects ofsource distance, quantity of powder, ignition sequence, construction method and geologicalcondition etc. on the ground vibration caused by the blasting are carefully analyzed. The general law about the intensity distribution of ground vibration caused by the blasting is summarized, which lays a foundation to find a point of balance between the dig blasting in the tunnel and the city environment on the ground.更多还原
