對具有任意厚度的靶,無偏折的通量隨厚度呈指數規律而衰減。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
結合採集到的大量爆破振動現場實測數據,並應用地震波的相關理論,分析了該地下工程開挖爆破的地面爆破振動特性及爆破振動對地面建(構)築物的影響;應用二元線性回歸分析法,通過matlab軟體計算得出該地下工程開挖爆破地震波的傳播衰減規律;分析結果表明,不同距離下的地面爆破地震波的衰減規律存在明顯的差異,近距離條件下爆破地震波的垂直方向分量衰減最慢,遠距離條件下垂直方向分量衰減最快,遠距離的爆破地震波的垂直方向分量和水平徑向分量的衰減指數均要比近距離相應的爆破地震波衰減指數要大。The change of dynamic pressure in the orientation of wave spreading follows the damping of e - index 6
