| 摘 要： | 应用有限元分析方法 ,分析计算了具有立交成因的原地重复地震的孕育机理 ,得出如下结论 :在第一个地震临震前 ,与发震断层平行立接的深部断层对发震断层有底劈作用 ,发震后深部断层会继续破裂传播 ,导致浅层的横向断层扭曲 ,从而使横向断层闭锁而孕育地震。

| Abstract: | The seismogenic mechanism of the in situ recurrent earthquake having stereoscopic cross cause is analysed and calculated with the finite elements method By analysing and calculating, it can be concluded that the deep upright fault that parallels the preparing earthquake fault has a diapirism to the preparing earthquake fault before the first earthquake After the earthquake, the deep fault will continue to splitting spread, so that the transverse fault is contorted to generate next earthquake |
