摘要
文章介绍了爆破振动的检测方法及主要过程,利用爆破振动时频分析得出某质点振动参数,利用动态应力理论将爆破振动对岩石作用转化为动态应力。以大理岩为例分析高应力条件振动波动态应力对岩石的反复压缩卸载过程,并指出在高应力条件下,爆破振动对岩石的破坏作用更加明显。
The method and main course of blasting vibration detection were introduced in this paper. Time-frequency analysis of a particle was used to obtain vibration parameters, and dynamic stress theory of rock blasting vibration role was applied to transfer the blasting vibration effect on rock into dynamic stress. Taking marble under high stress conditions as an example, shock wave dynamic stress on the rock of repeated compression and unloading process was analyzed, and it was found, that in high-stress conditions, damaging effects of blasting vibration on the rock become more pronounced.
