【摘要】 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。更多还原

【Abstract】 Some dynamic feature and effect of seismic waves by explosion are defined as seismic effects of explosion source. The methods and targets to appraise seismic effect of explosion source are put forward, including coherence function, converted coefficient of energy, attenuation factor of vibration time, spectra etc. The coherence function was introduced to analyse explosion for the first time. The physical principle and computational method of the aforementioned targets are represented. For the application, the experiment results of a certain charges are analysed and the data of the experiment shots from the DSS in the area from southwest of Shandong to north of Henan was dealt with, and they are basically identical. The method mentioned above will be useful for seismic exploration, seismic sounding, engineering seismics and seismic tomography.更多还原
