摘要(Abstract):

根据在迁安露天矿多次爆破震动监测所得的数据 ,研究了场地土层条件对建筑物爆破震动响应的影响 ,并从理论上进行了分析。实测结果和理论分析都表明 ,场地土层的存在和随着覆盖层厚度的增加 ,将使爆破震动响应增大 ,建筑物遭受破坏的可能性增高
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.
