摘　　要：以相似理论为基础,利用量纲分析法推导出模型试验应遵循的相似准则。构筑混凝土模型,进行不同大小抵抗线的单孔爆破试验,然后利用HHT分析方法从能量角度对爆破地震波衰减情况进行分析。通过对爆破地震波瞬时能量谱的分析,得出不同抵抗线爆破的地震波能量衰减变化情况。研究结果对降低爆破振动和提高炸药能量利用率具有一定的指导意义。Based on the similarity theory,the similarity criterion that should be followed in model test was deduced by using dimensional analysis method.The concrete model was constructed,the single hole blasting tests with different size resistance lines were carried out,and then the attenuation of blasting seismic wave was analyzed by HHT analysis method from the perspective of energy.By analyzing the instantaneous energy spectrum of blasting seismic wave,the attenuation of seismic wave energy with different resistance lines was obtained.The research results have a certain guiding significance for reducing blasting vibration and improving explosive energy utilization.
