|
摘要
根据含超压气体裂隙震源模式 ,分析了地球内部放射热能向孕震区积聚的过程 .建立了力学模型 ,对孕震区岩石弹性势能、位移势能、高能气体热能与地震波能量的转换作了定量分析 .分别推导出地震震级与震源尺度、地形变、地震矩、孕震时间的关系式 .所得结果与前人给出的相应公式和实际震例相符 .据此 ,从能量方面进一步验证了含超压气体裂隙震源模式 .
By using the seismic source model of crack containing hyperpressure gas,the course of radioactive heat energy in the earth to accumulate in the focal area and cause for earthquake are studied. The mechanical models are given.The quantitative analyses on transformation of elastic and displacement potential energies of the rock and heat energy of the gas in source area into seismic energy are made.The formulas between magnitude and focal size,deformation,seismic moments and seismogenic period are derived. The formulas tally with that of other men of learning and real earthquakes.The seismic source model of crack containing hyperpressure gas is verified further by energy.
