underground blasting meaning in Chinese

地下爆破
井下爆破

Integrated the monitoring data collected from the scene of blast with the correlative theory of earthquake wave , the blast vibration characteristic of this underground blast engineering and the influence that the blast vibration act on the ground buildings are analyzed . applied the method of duality linearity regression analysis , the propagation attenuational laws of blast earthquake wave in this underground engineering are gained by this software matlab . the analysis results indicat that the attenuational laws of blast earthquake wave are obvious diversity in the condition of difference distances
结合采集到的大量爆破振动现场实测数据,并应用地震波的相关理论,分析了该地下工程开挖爆破的地面爆破振动特性及爆破振动对地面建(构)筑物的影响;应用二元线性回归分析法,通过matlab软件计算得出该地下工程开挖爆破地震波的传播衰减规律;分析结果表明,不同距离下的地面爆破地震波的衰减规律存在明显的差异,近距离条件下爆破地震波的垂直方向分量衰减最慢,远距离条件下垂直方向分量衰减最快,远距离的爆破地震波的垂直方向分量和水平径向分量的衰减指数均要比近距离相应的爆破地震波衰减指数要大。
