伪三维有限元地震活动模型及其在华北地区的应用

Seismicity model of Pseudo-3D finite element and its basic application in North China

对伪三维地震活动模型做了进一步研究 ,主要是对无预设破裂方向的单元 ,引入应力摩尔圆方法来判定破裂发生的时间。该方法首先在一个简单的理论模型上加以应用 ,给出了一些计算结果 ,以检验所提方法的可行性。在此基础上 ,将这个模型应用到华北地区 ,得到了一些初步计算结果。这些研究结果为将地震活动的理论模型应用到实际地震活动中 。

The pseudo 3D finite element seismicity model is developed The main work is that the break occurrence time is determined by using stress Moore circle method for the cell with non assumed broken direction. The method is used on a theoretical mode, and some results are obtained. Based on these researches, the model is used in North China, and some preliminary results are obtained. These results provide a possible way to use seismicity theoretical model into practical seismicity.
