伴随强震的发生,震区常出现断层运动直接诱导的地表形变带(地震地裂缝)。它们的力学性质和展布格局为断层运动的研究提供重要的线索。本文根据道孚地震地裂缝的力学性质、组合规律和分布特征的分析,认为道孚地震的地表形变带是鲜水河断裂突然左旋运动并突然终止的结果。
With the occurrence of strong earthquakes, the surface deformation zone (earthquake ground fissure) induced by fault movement often appears in the earthquake area. Their mechanical properties and distribution patterns provide important clues for the study of fault movement. Based on the analysis of mechanical properties, combination rules and distribution characteristics of the ground fissures in Daofu Earthquake, the paper considers that the surface deformation zone of Daofu Earthquake is a sudden left-lateral movement of the Xianshuihe fault and abruptly terminates.
