| 摘 要： | 地震的孕育、发生与震源位置及其岩石力学性质有着密切的联系,本文借助数值模拟方法研究了岩石均质度在岩样变形直至破裂过程中对声发射事件活动状态的影响。数值模拟结果表明,岩石非均匀性对岩样声发射活动状态的时间演化过程有着较大影响,所得结论进一步支持了分区研究强地震前兆异常的必要性。 |

| Abstract: | The authors investigate the affections of the seismic state variation during the process of earthquake prognancy especially at a period of rock deformation prior to the fracture due to rock heterogeneity by means of the numerical simulation because of the fact that the pregnancy and occurrence of the earthquake have close relation with the location of the earthquake and the material around it.The results of the simulation show that the rock heterogeneity can affect the sequence of the acoustic emissions greatly,leading to the variation of seismic state before the fracture.The conclusion supports the necessity of studying precursory features based on the different geological areas. |
| Keywords: | Rock Heterogeneity Seismic state variation Numerical Simulation Earthquake prediction |
