Abstract: This paper is based on the geological hazard monitoring, the early warning work, the monitoring data analysis and the information system construction examples of geological hazards in Three Gorges Reservoir area. It focuses on the concept and connotation of geological hazard monitoring data analysis, and the development trend of geological hazard monitoring data analysis. The main findings are as follows. (1)The definition of geological hazard monitoring data analysis is put forward. It is the comprehensive analysis of geological hazard monitoring data and related achievements and data according to the purposes, contents and methods of geological hazard monitoring. (2)In the face of multi-source, heterogeneous, real-time, massive geological hazard monitoring data, the development of intelligent geological hazard monitoring data analysis system is the key to solve the problem. The system can integrate the geological hazards monitoring big data, the various analytical techniques, methods and application service systems as well as the workflow of monitoring data analysis.
