摘要
根据3次分段微差爆破的现场观测结果,对爆破地震动强度与炸药量、爆心距的关系,以及最大允许炸药量与危险区半径的确定,给出经验公式。同时结合场地衰减系数、炸药能量转换和减震效应等作了初步探讨。
The experience formulas are given in this paper about the relations between the intensity of ex- plosion earthquake ground motion and explosive charges,distance from explosive source,as well as the determination of maximum allowable explosive charges and radius of risk regions,based on the re- suits of the in-situ observations of three segmented explosions with very short time-separation inter- val.Preliminary investigations are made together with site attenuation coefficient,transformation of explosive energy and shock-absorbing effect.
