本文把爆炸源产生的地震波的某些动力学特性及效果定义为爆源地震效应,提出了用以评价爆源地震效应的方法及指标:凝聚函数、能量转换系数、振动时间衰减因子、频谱特性等,其中凝聚函数是首先引入到爆源分析中並给出相应计算方法的。本文介绍了上述指标的物理含义及求取方法,分析处理了某种炸药对比试验结果及鲁西南—豫北人工地震测深中的试验炮资料。所得结果为爆源综合评价提供了基本定量依据。本文所提出的分析方法,可以在地震勘探、人工地震测深、工程地震和地震波透视研究申应用。
In this paper, some dynamical characteristics and effects of seismic waves generated by explosion sources are defined as seismic effects of explosion sources. Methods and indicators for evaluating the seismic effects of explosion sources are proposed: condensation function, energy conversion coefficient, vibration time attenuation factor, spectral characteristics Among them, the condensation function is first introduced into the explosion source analysis and gives the corresponding calculation method. This article introduces the physical meaning of the above indicators and methods to obtain, analyze and deal with the comparative test results of certain explosives and experimental gun data from the Southwest-North Artificial Earthquake Soundings. The results provide a basic quantitative basis for the comprehensive evaluation of explosive sources. The analysis method proposed in this paper can be used in the seismic exploration, artificial seismic sounding, engineering seismic and seismic wave research.
