【摘要】 在地形起伏较大的情况下,地形地貌对爆破振动波的传播具有较大的影响。通过分析与爆破振动有关的物理量,运用量纲分析法推导了反映高程放大效应的爆破振动公式。结合现场爆破振动监测,当爆破场地的地形地貌变化较大时,用传统的萨道夫斯基公式预测爆破振动速度误差较大,其平均误差达42%～59%,其他4个常用经验公式预测的平均误差,分别为24%～49%、40%～58%、58%～59%、31%～39%;而采用量纲分析法推导的公式预测爆破振动速度误差较小,其平均误差仅为10%～14%。研究结果表明,通过量纲分析法得到的爆破振动公式能较准确地反映正高程差放大效应。更多还原

【Abstract】 Topography affect greatly propagation of vibration wave under condition of variety of terrains.Through analyzing the physical quantity of blasting vibration,a blasting vibration formula of reflecting amplification effect on elevation is established by means of dimensional analysis.Based on the field test of monitoring blasting vibration,when the site topography changes greatly,the velocity error is large by conventional Sodev’s empirical formula,and the average is 42%-59%.The average error of velocity of blasting vibration is respectively 24%-49%,40%-58%,58%-59% and 31%-39% with other four practical formulas.The velocity error is small with author’s formula of dimensional analysis;and the average error is only 10%-14%.It is shown that the formula of blasting vibration which is established by means of dimensional analysis can accurately predict amplification effect on positive elevation.更多还原
