摘要
为正确理解和使用Sadovki爆破地震衰减公式,研究了Sadovki爆破地震衰减公式中的k、α场域分布特征,运用灰关联分析方法,确定了分段装药量、爆心距、地形、岩性、微差间隔时间依次是影响爆破地震的主要因素,从而为台阶爆破合理设计与施工提供了理论依据。该理论也可作为其他为确保边坡稳定进行爆破开挖设计的理论依据。
To correctly understand and use the formula for blasting vibration attenuation, K, α.field distribution in Sadovki formula for blasting vibration attenuation is studied. Grey relational analysis is used to determine the weighing of the main factors influencing the blasting vibration such as sublevel explosive charge, distance to explosive center, terrain, lithology, microsecond delay time, thus providing a theoretical basis for the reasonable design and construction of bench biasring.
