本文根据短基线、短水准等测量资料,把唐山地震前后京、津、唐附近活动断裂的运动划分为震前加速、震时滑动和震后调整三个阶段,分析了各阶段的速率变化、活动性质和时空分布等特征,据此讨论了主要由地震蕴育、发生引起的活动断裂位移异常区的构造背景。最后,讨论了它们在地震预报和烈度区划工作中的意义。 Based on the short baseline and short leveling data, the movement of active faults around Beijing, Tianjin and Tangshan before and after the Tangshan earthquake is divided into three phases: acceleration before the earthquake, slip after the earthquake and post-earthquake adjustment, and the changes of the velocity in each phase are analyzed. The nature of activities and the distribution of time and space. Based on this, the tectonic setting of anomalous areas of active fault dislocation mainly caused by the occurrence of earthquakes is discussed. Finally, the significance of them in earthquake prediction and intensity zoning is discussed.
