爆破振动衰减规律的现场试验研究
Experimentally Study on the Attenuation Law of Blasting Vibration
【摘要】 爆破振动衰减公式中的K、α取值,受爆破方法、地形地质条件等影响较大。根据同一地区小型爆破试验和现场工程实测所获得的衰减公式中的K、α值,分析、探讨了不同条件下爆破振动衰减公式的变化规律。试验结果表明,即使在同一地区,应用回归的衰减公式指导爆破设计和施工时,也应加以试验条件的限制,从而使爆破地震波的预测、预报更加符合实际。
【Abstract】 The conditions of blasting and landform have a tremendous influence on the value of K and α of blasting vibration attenuation formula.According to the small experiment and project to obtain value of K and α of attenuation formula.Different conditions of change law are compared and analyzed.Experimental results show that application attenuation formula to direct design and construction of blasting should meet the requirements of limit of experiment condition,to make the forecast of earthquake waves more accurate.
