| Abstract: | Based on the data gained in blasting vibration monitoring in Qianan Open Pit,the effect of ground conditions on the response of building to blasting vibration is researched and analyzed theoretically.Both monitoring result and theoretical analysis have proved that the thicker the ground soil become,the bigger the response of building to blasting vibration and the higher the probability of building damage. |
