摘要
断层带应变弱化——失稳的地震模式表明,岩体失稳不仅取决于作用的应力水平,而且决定于应变弱化阶段中环境刚度和岩石刚度的相对大小。该模式可能被应用去解释实际观测中出现异常,而其后不发生地震活动的复杂情况。
The Seismic Model of strain weakness-instability along fault zone shows that the rock instability depends on not only the acting stress level but also the relative intensities of environment and rock rigidities during the strain weakening stage. The model might be used to explain a complex case in which real precursory anomalies have been observed, but no earthquake occurs afterward.
