摘要
当前岩体中地震波传播规律还无法从理论上给出的统一公式。而主要依靠工程实测来获取第一手资料,然后通过最小二乘法来拟和经验公式对地震波的强度进行预测,从而达到防震减灾的目的。本文通过编制程序,对各种形式的拟和公式进行了比较,对爆破振动速度衰减公式的优化选择进行了探讨。根据不同形式拟和误差的不同,提出应解除萨氏公式中一次起爆药量与爆心距指数比例,选择最优化的指数来模拟,从而使得预测结果更加符合实际。
Presently, rule of seismic transmission still can’t be given accurately in theory. Usually primary information is attained from engineering measurement, then an empirical equation is simulated according to the least squares theory to prevent and reduce disasters. In this paper, different formula forms are compared through programs and optimization selection of blasting vibration velocity attenuation formula is investigated. According to the different error rates of different formulas, the index number of the charge and the distance should be released in empirical equations, and an optimized index number should be searched in simulation of the equation to make the prediction more accurate.
