| 摘 要： | 在讨论地震地质背景基础上，综合分析了震区的深部构造、地表活动断裂、地面形变、极震区展布方向、震害、余震分布、震源机制解等发震构造标志，并且进一步探讨了发震机制。初步认为北北西向罗明坝－太平断裂和北东向飞陵－丙麻断裂是2001年施甸地震的主要发震构造，二者具有共回轭构造活动的特征。

| Abstract: | Based on the discussion of the seismogeological setting in this paper, the seismogenic structure marks were synthetically analyzed, such as the deep structures, ground active faults, ground deformation, meizoseismal region direction and hazard, post-earthquake distribution, focal mechanism solution in the earthquake area. And further, it discussed the seismogenic mechanism. It is considered that Loumingba-Taiping fault in the direction of NNW and Longling-Bingma fault in the direction of NE are main seismogenic faults of Shidian earthquake in 2001. The two faults have features of activity of conjugated structures. |
