爆破振动多采用萨道夫斯基经验公式法预测,但由于影响爆破振动效应因素较多,导致回归系数离散程度较大.尤其在保护重要对象时,若采用单一的衰减公式,可能存在安全隐患或降低施工效率.结合一起为保护古建筑进行的爆破振动监测,利用多组爆破试验数据进行回归分析,充分分析不同组合的回归结果.针对不同的爆破条件选用相应的衰减系数,科学地预测爆破药量.不仅有效地控制了爆破振动,而且提高了施工效率.

The vibration velocity is usually predicted by Sadov′s empirical formula,but since too many factors influence the vibration,the dispersion of regression coefficient is relatively serious.Particularly,in protecting important objects,there will be some safety trouble hidden or lower construction efficiency if using just an attenuation formula.Combining blasting vibration monitoring for protecting ancient architecture,many test data of blasting were regressively analyzed,and also analyzing fully the different results.We chose relevant attenuating coefficient based on different blast condition and scientifically predicted the explosive amout.All of those not only efficiently control the blasting vibration,and also improve the construction efficiency.
