【摘要】 本文通过实际资料的分析，将江苏省及邻近地区发震断层力学性质的分布划为两个区，Ⅰ区为南黄海海域及其沿海地区，发震断层的力学性质以逆断层和兼具冲断运动形式的平移断层为主，约占发震断层总数的７０％；Ⅱ区内发震断层以平移断层和正—平移断层为主要成份，占总量的７９％，两者形成鲜明的反差。文章分析了产生这种分区现象的地震营力来源，指出这种分布特点具有的工程学意义。更多还原

【Abstract】 Distributions of mechanical behaviors of seismogenic faults in Jiangsu and its neighboring areas have been divided into two zones. Zone Ⅰis the South Yellow Sea and its coastal areas where the mechanical behaviors of seismogenic faults are mainly reversed and translational with thrust taking 70% of the total seismogenic faults. Faults in zone Ⅱ are mainly the translational and right-translational taking 79% of the total which are totally different from zone Ⅰ. Seismic agent source producing zoning phenomina is analysed which demonstrates the significance in engineering.更多还原
