Abstract：On the basis of the calculated results of the leveling data of Tianjin area during 1992-2008，the vertical variations of the ground were studied and the funnels of every survey line were calculated by polynomial function as well.After eliminating the settling influence of the groundwater pumping，the results are then fitted individually in each block，the diagrams of the vertical deformation rate were mapped，and the vertical velocities of the main fault zone were calculated.On the basis of the results of the studies the activities of block and fault zone in Tianjin were investigated.The vertical deformation reflects that some blocks in the Tianjin appear tilting and some appear rise or fall.The vertical variety divergences are different.The vertical velocity of the fault zone in Tianjin area is between 0.13-0.48 mm/a，the average velocity is 0.29 mm/a.
