摘要/Abstract

摘要： 本文通过对1976年7月28日唐山大震前京、津、唐地区多期复测水准资料的分析,揭示出唐山大震前、后地壳形变的演化过程,并进而讨论了一个大地震在孕育过程中可能出现的三个地形变标志。

Abstract: Analyses of data for the crustal deformation before and after the Tangshan earthquake indicate an evolution of the crustal deformation. Three signs may have emerged from the process of the preparation of a strong shock:1. rapidly increasing regional stress field;2. occurrence of intensively active structures and change of the regional stress field and;3. formation of concentrated deformation points on the seismogenic structures. From the signs of crustal deformation,it is believed that east of Daofu may be asegment of the potential earthquake.
