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。 - Finally , the problem of exponential filters for nonlinear time - delayed systems is considered . the filters designed by using the given approach can guarantee the stead - state and transient performance . by choosing suitable attenuation index , the perfect performances of filters can be attained
