摘要(Abstract):
采用灰关联分析法对爆破震动参数的主要影响因素进行了分析 ,建立了各因素与爆破震动参数之间的灰关联度矩阵。通过对灰关联度矩阵的分析 ,得到了影响爆破震动强度的主要因素 ,其中 ,爆破点与测点之间的高差为影响爆破震动参数的准优因素 ,在进行爆破震动参数预报时 ,必须充分考虑其重要性。
By grey correlation analysis, main influencing factors on blasting vibration parameters were studied and a grey correlation matrix of these main factors and blasting vibration parameters was established. Through analyzing the grey correlation matrix, main factors of affecting blasting vibration were obtained. Of these factors, the height difference between blasting and monitoring spots is the quasi dominant factor. Therefore, its importance must be well taken into account when predicting blasting vibration parameters.
