动态库仑破裂应力变化的模拟计算及断层类型影响研究
|
摘要
对走滑断层、逆断层破裂产生的动态库仑破裂应力变化进行了模拟计算,得到了动态库仑破裂应力变化的空间分布图像。分析结果显示,不同类型断层破裂所产生的动态库仑破裂应力变化,其分布图像有很大区别。
Through calculating the dynamic Coulomb rupture stress changes caused by strike-slip fault and reversed fault,we obtained the space distribution image of dynamic Coulomb rupture stress changes.The analytical result indicates that the distribution image of dynamic Coulomb rupture stress change produced by different types of faults is very different.
