  1. 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,不同離下的地面爆破地震波的衰減規律存在明顯的差異,離條件下爆破地震波的垂方向分量衰減最慢,遠離條件下垂方向分量衰減最快,遠離的爆破地震波的垂方向分量和水平向分量的衰減指數均要離相應的爆破地震波衰減指數要大。
  2. Comparing the catchments with the same conditions at the same scales, we found that at the small scale catchments, the factor directly impacting the runoff variation and sediment variation was the relative distribution location at sloping fields, and at the median scale catchments, was the slope distribution of land use components, while at the large scale catchments, the distance distribution of land use components

    在相條件的同尺度集水區之間較發現,小尺度集水區土地利用類型的坡位分佈格局對流和泥沙變化有較接的影響,中尺度集水區土地利用類型的坡度分佈格局和大尺度集水區的土地利用類型的離分佈格局對流和泥沙土地利用空間分佈格局對侵蝕產沙過程的影響的變化影響較大。
