| 摘 要： | 基于小波包爆破地震能量分析法和损伤力学基本理论,对低频爆破震动对岩石的破坏作用进行了分析,提出了震动对岩石的拉压损伤作用理论,从能量角度解释了岩石破坏原因,克服以往岩石破坏判据单一的缺陷,得出低频爆破震动破坏岩石的普遍理论,为以后进一步研究提供了依据。

| Abstract: | Based on wavelet packet analysis of blasting seismic energy and the basic theory of damage mechanics,this paper analyzes the damage effect of blasting vibration with low frequency on rock,and introduces a theory that blasting vibration has the damage effect of tension and compression on rock,which explain the reasons of rock damage from the perspective of energy,and overcome of single criterion for rock damage.The summarized universal theory about damage effect of blasting vibration with low frequency on ro... |
