介绍了设于唐山地震发震断层地表裂缝的形变台站，在地震后１８年间观测到的断层形变．结果表明，发震断层的垂直和水平形变都集中在大震之后的７年之内；１９８３年是震后形变的转折期．大面积水准显示的形变与断层形变强度定性相符，目前呈现出不易于积累应力的松弛状态，近期不大可能发生较强地震．
This paper introduces the deformation station of the deformation at the surface crack of the seismogenic fault in Tangshan earthquake and the fault deformation observed in the 18 years after the earthquake. The results show that the vertical and horizontal deformation of the seismogenic faults are all concentrated within 7 years after the earthquake; 1983 is the turning point of post-earthquake deformation. Deformation of a large area shows qualitatively the same as that of the fault deformation. At present, there is a relaxed state that is not easy to accumulate stress, and a strong earthquake is unlikely to occur in the near future.
