- 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.
