| 摘 要： | 地震断层破裂在周围固体介质中能产生静态附加应力场.当依据库仑破裂准则和破裂模型推测构造应力变化,用以判断能否触发某处断层破裂时,这种应力变化称作"库仑破裂应力变化".一次地震产生的"库仑应力变化"被认为能影响下一次地震的发生.讨论了计算"库仑应力变化"所采用的不同模型,指出伏尔泰拉错动模型不能真实反映震源参数,因而所给...

| Abstract: | Seismic fault failure can generate additional static stress in surrounding solid medium.The stress change,calculated by using certain fault model and following Coulomb fracture criteria,with the aim at testing if it can trigger other fault failures,is called Coulomb failure stress(CFS)change.It is commonly believed that the CFS change generated by an earthquake can affect the occurrence of other remote earthquakes.This paper examines and compares the calculations of CFS change in using three different model... |
