摘要:
应用地理信息系统(Geographical Information System ,GIS)技术在对某滑坡地质灾害进行现场调查统计的基础上,应用刚体极限平衡分析法(SARMA)及有限元法(FEM)对该滑坡的稳定性进行了分析研究;采用灰色系统理论方法对滑坡的发生趋势进行了预测,开发研制了基于GIS的滑坡地质灾害预警预测系统.系统运行结果表明:该滑坡的稳定性较好,水对该滑坡体稳定性影响较大;开发完成的滑坡地质灾害预警预测系统实现了地质灾害有关数据的统一管理和预测;构建完成的滑坡地质灾害三维模型能够准确地反映灾害发生地的地质地貌情况;该系统为实现地质灾害网络地理信息系统(WebGIS)进行资源共享打下了坚实的基础.
Abstract:
The CGIS technique is used to investigate the statistics of landslide geological disasters,and the gridlimit equilibrium method and finite element method (FEM) are used to analyze stability of the landslide,andthe gray system theory method is used to forecast deformation trend of the landslide,and the early waning sys-tem about landslide geological disasters is completed.System operation results show that:the stability of thelandslide is good,the influence of water on the stability of the landslide is bigger;the early warning system a-bout landslide geological disasters which is developed realizes unified management and forecast of the relateddata of geological disasters;the constructed 3D model of landslide geological disasters can accurately reflectthe geological and topographical feature situation of where the disaster happened; the system has laid a solidfoundation to realize sharing of the WebGIS of geological disasters resources.
