摘　　要：利用1984～2008年唐山台跨断层基线和水准数据，分时段研究断层的运动特征，计算出唐山断裂水平形变、垂直形变特征及断层活动速率。求解断层及周边地区的的应变特征和主应变方向，研究唐山断裂的活动特征。探讨唐山断裂活动与地震活动的关系。In this paper, cross- fault baseline data and leveling data in 1984 -2008 from Tangshan seismological station is used to study the motion characteristics of the Tanshan faults during different period of time. The vertical and horizontal deformation of the fault is calculated, the motion rate of it is given. On this basis, the relationship between the seismic activity and activity of the fault are discussed.
