本文据我国地震震源机制解的结果,以节面侧伏角大小,两盘块体相对运动形式和节面倾角大小为基础,讨论了我国地震断裂的力学特点和分类,以断裂滑动类型,块体相对运动和断裂倾角三个要素为准,进行对地震断裂的联合命名。最后在分类统计的基础上扼要地讨论了我国地震断裂的基本特点。 Based on the results of earthquake focal mechanism solutions in China, the mechanical characteristics and classification of seismic fractures in China are discussed based on the nodal size of the nodal plane, the relative motion of the two plates and the nodal angle, Relative motion and fault dip angle shall prevail, the joint name of the earthquake rupture. Finally, based on the classification statistics, the basic characteristics of earthquake rupture in China are briefly discussed.
