三峡水库的形成将面临着水库的正常运行和现有城镇安全的两大方面问题 ,并突出表现在三峡库区沿江岸坡的稳定性上。利用地理信息系统 (GIS)及相关技术手段对“三峡库区滑坡泥石流预测预报 3S系统”中的关键问题进行了研究 ,主要工作有如下 7个方面 :( 1)确立了滑坡地质信息GIS可视化空间数据库的建立途径与方法 ,建立了滑坡体GIS地质信息数据库 ;( 2 )开发了二维地质信息与三维地质信息的相互转化技术 ;( 3)确立了地质界面三维插值及滑坡三维地质信息模型建立的新方法 ;( 4)进行了滑坡三维地质信息模型的GIS工程解析工作 ;( 5 )利用GIS的程序设计语言 ,探讨了在GIS中实现滑坡体稳定性力学解析计算的可行性 ;( 6 )开发了GIS与数值解析系统接口技术 ;( 7)探讨了GIS在移民选址中的应用
Three Gorges Reservoir will face the normal operation of the reservoir and existing two major aspects of urban safety issues, and highlighted the stability of the banks of the Three Gorges reservoir along the bank. The key problems in “3S System of Landslide, Debris Flow Forecast in the Three Gorges Reservoir Area” are studied by using Geographic Information System (GIS) and related technologies. The main work has the following seven aspects: (1) Establishing the GIS visualization space of landslide geological information (2) developed a mutual transformation technology of 2D geological information and 3D geological information; (3) established three-dimensional geological interface interpolation and establishment of 3D geological information model of landslide (5) Using the programming language of GIS, the feasibility of implementing the analytical calculation of the stability of the landslide body in GIS is discussed; (6) By using the GIS programming language, Developed GIS and numerical analysis system interface technology; (7) discussed the application of GIS in immigration site selection
