| 摘 要： | 引入中国大陆构造应力场资料，结合区域构造及断层运动特征，根据岩石力学原理确定优质破裂面，对走滑断层、正断层和逆断层３种主要断层运动形式，推导了有效剪应力表达式；提出了新的加卸载判定，并对部分震例进行了再研究。 |
| 关 键 词： | 加卸载响应比 构造应力场 优势破裂面 地震预报 |

| Abstract: | Based on the characteristics of regional fault activity and the result of tectonic stress field,the dominant plane of fracture is proposed according to the principle of rock mechanics.A formula of effective shear stress is deduced for the slip fault,the thrust fault and the strike fault.And some earthquake cases are studied again according to a new Loading/Unloading distinction criterion. |
| Keywords: | Loading/Unloading Response Ratio\ Tectonic stress field\ Dominant plane of fracture\ Effective shear stress |
