摘要
声波测试广泛运用于复核开挖岩体质量、检验开挖爆破效果等多个方面,本文针对开挖岩体爆破前、后波速对比时出现的波速变化异常问题进行分析讨论,阐明产生波速异常的根结所在,并提出防止类似问题出现的应对措施。
Sonic test has been widely applied to many aspects, such as checking up the rock mass quality and effection of Excavation blasting. This paper mainly discusses and analyses the abnormity of sonic contrast between pre blasting and afte-blasting in allusion to the excavation blasting rock body. Reason of the sonic abnormity has been clarified. Then, measures to deal with this problem are put forward.
