摘要
Using the data of cross-fault baseline and leveling recorded by Tangshan Stations from Jan. , 1999 to Sep. , 2012, the horizontal and vertical deformation and fault activity rate of Tangshan Fault are calculated. By solving the local strain characteristics and principal stress direction, the relationship between Tangshan Fault activities and seismic activities is discussed. The results show that large earthquake in remote field and local moderate strong earthquake may have a certain influence on the horizontal and vertical movement of the Tangshan Fault, and the stress field of the Tangshan Fault and its surrounding area may have great changed in 2003.
