摘要
本工作首先借助连续体物理理论方法,依据如下三条基本假定:①地壳潜断层或相变区域是聚集、致锁地震能源的基础;②震源体是由粘性、塑性、弹性碎裂演化成的;③大气压异常可以提供临震的临界荷载;由此提出云南板内地震的孕震方程.接着在探索此方程的整体性质中,揭示出云南浅源地震灾害里的临界特征.最后还给出一些临震预报的思路和方法.
The oregnant equation of earthquake has been given firstly by the theore i-cal method of the continuous medium physic. Besides the three basic hypothesses are is follows: ①The potential fault, or the phase changed material, is the material of collecting and locking eathquake energy. ②The earthquake hypocenter is a kind of viscous-plasticelastic body. ③The anomalous atmospheric pressure can be used as the cntical loading of the earthquake foreshock. Secondly, the integral property of the equation has been discussed, and the characteristics of seismic catastrophe has been explored n Yunnan's great earthquake. Some ideas and methodes of earthquake forecast have been finally given in this paper.
