Abstract:

The numerical simulation result and monitoring data have been integrated so as to study dynamic assessment of induced earthquake in the head area of Three Gorges Reservoir. The technical route was that the results of numerical simulation have been evaluated by professional earthquake model. The findings of the evaluation have been regarded as its background database which has been updated with real-time earthquake monitoring data, groundwater level monitoring data and crustal deformation monitoring data. The risk assessment system of induced earthquake has been studied by simulation tools of FLAC 3D, MAPGIS as its basic platform and VC++ as the developing tool. The research results show that the evaluation indices of numerical simulation model and monitoring data can be integrated by information fusion technique on GIS platform; so that a dynamic assessment of reservoir induced earthquake can be achieved.

Key words: geographic information system, information fusion, numerical simulation, monitoring, induced earthquake, risk assessment, dynamic assessment
