摘要
爆破所引起的一系列负面效应,特别是爆破地震波的负面效应也越来越受到人们的关注和重视,往复爆破作业产生的岩体损伤效应更为突出。为此采用BlastMateⅢ型爆破测震仪,进行循环爆破加载下工程岩体的损伤试验,试验数据具有较好的相关性,爆心距与PPV成反比例的关系。
A series of negative effects caused by blasting,especially the negative effects of blasting seismic wave become more and more concern and attention of the people and the damage effect of reciprocating blasting of rock mass is more outstanding. Accordingly,engineering rock mass damage experiment through BlastMateⅢ blasting vibration meter under circulating blasting load was carried out,the experiment data have good correlation and the distance from the blasting center is inversely proportional to PPV.
