RESEARCH ON DYNAMIC CHARACTERISTICS OF LAND SUBSIDENCE
IN TIANJIN USING LEVELING DATA
1）First Crust Monitoring and Application Center, CEA, Tianjin 300180
Abstract We use the leveling data from 1998—2006 to analyze the dynamic characteristics of land subsidence in Tianjin. The results show that the land subsidence is larger in south of Tianjin than that of north, which the subsidence rate is very small from north boundary of Tianjian to 39.3°N, and the subsidence rate is large from 39.3°N to the south boundary. The results of multisection reveal that the subsidence rate is large in the east region of middle Tianjin from 1998—2002, while it decelerates from 2002—2004 and it increases from 2004—2006.
