本文引入灰色系统理论的关联分析方法,对油田罐区21次土石的爆破效应进行了多因素灰色关联分析。通过计算关联系数,求关联度,给出了关联序。研究结果客观地揭示出土石爆破产生的地面震动速度与爆破参数之间的关系,其量化结果进一步反映出土石爆破的地面效应中各参数之间关系的疏密程度,指出药孔的深度对地面震速的影响大于药量、测点距离对震速的影响。
This paper introduces the grey system theory correlation analysis method, and carries out multi-factor gray correlation analysis on 21 blasting effects of soil and rock in oil field tank area. By calculating the correlation coefficient, the correlation degree is calculated and the correlation order is given. The results of the study objectively revealed the relationship between ground shaking velocity and blasting parameters caused by earth-rock blasting. The quantified results further reflect the degree of density of the relationship between the parameters in the ground effect of earth-rock blasting, and pointed out that the depth of the drug hole is on the ground. The influence of the speed of vibration is greater than the effect of the amount of drug and the distance of the measuring point on the speed.
