摘要:: 从弹性力学、断裂力学角度,以总应变能预测研究块体地震活动,并从岩石破坏试验结果论述这种预测研究的实验依据,最后结合实例证明,用块体应变能积累释放进行强震活动预测研究在实际应用中的可行性。这种分析研究方法可能对地震危险区及最大震级预测有实际应用价值。

Abstract:: The theory basic of studying and predicting the strong earthquake using total strain energy in the whole geologic block was analyzed by elasticity mechanic and fracture mechanic, and the experimental basis of the predicting research is discussed by the test result of rock failure. Then combined with the actual example, the feasible of the research method was verified in the real application. The research method may have the practical application value for predicting the seismic risk region and the magnitude of strong earthquake.
