Abstract

On the basis of in situ investigation and deformation monitoring of the Jijia River landslide (JJRL), the rigid body limit equilibrium method and finite element method (FEM) were used to analyze the stability of the JJRL; the grey system theory method was applied to forecast the deformation trend of the JJRL; and the information system about the landslide deformation and monitoring, and forecasting systems based on the platform of the Web Geographical Information System (WebGIS) were developed, which can be used to analyze in situ monitoring data and predict the deformation of the landslide. The study results can be summarized as follows: ➀ the JJRL is stable as a whole; the water content in the landslide has a great effect on its stability; ➁ the developed Web Geographical Information System has realized many functions, including inputting, computing, inquiry, analyzing, and the function of forecasting; it has also realized the functions of distance data management, analysis, and forecasting based on the WebGIS; ➂ the information resource can be shared by the WebGIS developed all over the world.
