| 摘 要： | 研究了二维粘弹性介质中平行走滑断层的相互力学作用及其地震活动性的影响。当一条断层发生滑动，将导致平行断层面上剪切应力减小，因此，可能推迟平行断层发生滑动，推迟时间在几年至几百年的范围内，这取决于发生滑动的断层与平行断层之间的距离，以及平行断层自身应力积累孕育地震过程经历的时间。

| Abstract: | The interaction between parallel strike slip faults and its effect on seismicity in visco elastic model is in vestigated. The slipping along a strike slip fault would lead to shear stress reduction on parallel fault planes, and delay the slip occurrence along the parallel faults (i.e. seismicity reduction effect). The delay time would range from several years to several hundreds years, which depends on the distance between the slipping fault and parallel faults, and the elapse time of stress accumulation process on parallel faults. |
