北京地区断层的活动

应用断层位移测量资料,对北京地区断层的话动性作了初步分析,表明一些跨主要断层所布设的短基线、短水准观测成果,在1976年唐山地震的孕育、发生过程中,显示了较为明显的错动,而不跨断层的测量结果则显示无错动或错动很少;不同断层的不同部位,其活动性则有相似也有差异.

ON FAULT DISPLACEMENT IN THE PEKING DISTRICT

By using the fault displacement data obtained by geodetic surveys, an analysis of the fault activity in the Peking district was made. It has been demonstrated that during the processes of preparation and occurrence of the earthquakes in the Tangshan area （1976） and other localities, the results of short-range base line and levelling surveys across some principal faults indicate clearly their dislocation while from surveys not made across the faults, no or only a little dislocation can be observed. Along various segments of different faults, their activity may be similar or different.
