波形特征与层理岩石各向异性关系分析
|
摘要
岩石声学特性可以对岩石内部结构及力学特性进行描述与分类。通过对岩石声学特性的研究可以得到岩石爆破破碎所需的诸多信息。通过试验分析可知,声波速度与岩石爆破破碎效果密切相关,且岩石波形与岩石声波速度密切相关。声波波形与岩石破碎特征存在一定的相关性,波形在岩石不同方向上的差异性与岩石在不同方向上爆破破碎效果的差异性是相关的。
The research on acoustic characteristics of rocks is thought to be a fairly reasonable approach which will reflect the insight details of texture and mechanical properties of rocks.According to the study of acoustic characteristics, a lot of information can be learned which can be used in rocks blasting.Some acoustic experiments were conducted on layered rocks,it is closely related between acoustic velocity and rock blasting fractured results,and the waveform of sonic wave is tightly correlated with the acoustic velocity.Obviously,in some sense,the acoustic waveform characteristics and rock blasting fractured results could be correlated in some way.So the differences of the waveform in rock's different directions and the differences of rock blasting fractured results in different directions are to some extent correlated.
