本文分析了各种地震预测方法对地震的预测情况.首先通过岩石力学实验和有限元模拟计算结果分析了含裂纹岩石材料的变形破坏过程;其次,将实验室岩石破坏过程的观测结果和有限元模拟计算结果外推到地壳岩石的变形破坏过程,从地震发生的物理力学机理出发,对多种地震预测方法进行了评述,研究这些地震预测方法的有效性和尚待解决的问题,同时对利用物理化学方法预测地震的前景进行了讨论.
In this paper, we analyze the prediction of earthquakes by a variety of earthquake prediction methods.Firstly, the deformation and failure process of cracked rock materials is analyzed by rock mechanics and finite element simulation results.Secondly, the observation results of laboratory rock failure process and finite element The simulation results are extrapolated to the deformation and failure process of the crustal rocks. Based on the physical and mechanical mechanism of the earthquake, a variety of earthquake prediction methods are reviewed, the effectiveness of these earthquake prediction methods and the problems to be solved are studied. At the same time, The physico-chemical method to predict the prospect of earthquakes is discussed.
