| 英文摘要 | Monitoring the ground deformation concerns the safety of gas storages much. The ground deformation in salt cavern gas storage area is characterized by spatial diversity and temporal nonlinearity owing to the spatial distribution of salt caverns and the cyclic variation of stress environment. A technique with high spatial and temporal monitoring density is therefore needed to fully reveal the spatial and temporal characteristics of the ground deformation in salt cavern gas storage area. Based on permanent scattered interferometry (PSI) technique, the ground deformation history in Jintan salt cavern gas storage area from 2007 to 2010 was retrieved using PALSAR data. Compared with GPS data, the PSI results are found to have higher accuracy in both reflecting the general trend and the nonlinear process of ground deformation, and to have higher monitoring density in both spatial and temporal domains. The ground deformation in Jintan gas storage area presents obvious spatial patterns. Area with high settlement velocity corresponds to the area with intense human engineering activities. In addition, nonlinear behaviors were found in the ground deformation history in Jintan gas storage area; and this deformation history could be divided into three stages of settlement and two stages of uplifts. However, owing to insufficiency of relevant data, the problem that whether this fluctuation between settlement and uplift is attributed to human activities requires further research. |
