本文根据马头山石灰岩矿四次爆破地震动效应的观测结果,给出了爆破地震动水平加速度最大值与炸药量、爆心距三者之间的关系。并对地震动最大位移衰减规律、爆破地震动的频率特征及炸药能量转化为地震波能量的转换系数等作了初步探讨。
According to the observation results of the ground motion effect of four explosions in the limestone mine in Matou Mountain, the relationship between the maximum horizontal acceleration of blasting ground motion and the amount of explosives and the center of the explosion is given. The attenuation law of the maximum displacement of ground motion, the frequency characteristics of the blasting ground motion and the conversion coefficient of the explosive energy converted to the seismic energy are discussed.
