| 摘 要： | 将数值模拟成果与监测数据集成，对三峡水库库首区诱发地震危险性进行了动态评价。在GIS (geographic information system) 平台上将数值模拟结果用专业地震模型进行评价，其成果作为评价背景数据库。用实时的地震监测数据、地下水位监测数据、地壳形变监测数据对背景数据库进行更新。选用FLAC 3D为数值模拟工具，MAPGIS为GIS基础平台，VC＋＋为开发工具，研发了水库诱发地震危险性动态评价系统。系统提供在一定蓄水位条件下、一定评价范围、一定深度内的水库诱发地震灾害危险性区划。研究结果表明，在GIS平台上，利用信息融合技术，可以将水库诱发地震的数值模拟评估、监测数据评估进行集成，实现水库诱发地震危险性动态评价。

| 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. |
