Research on Monitoring and Warning of Collapse Geological Hazards
Collapse is one of the most common geological disasters in China,and it is also the most important sudden geological disaster in Shanghai. In order to minimize the social and economic losses caused by the collapse geological disasters,this study analyzed the failure mode and cause mechanism of the collapse geological disasters by means of field survey,data investigation and numerical simulation,and subdivided the collapse geological disasters in the mountain area of Shanghai into three categories and five sub-types. According to the classification of collapse hazards,this paper puts forward the monitoring contents,methods and monitoring points of collapse geological hazards,and obtains dif-ferent types of collapse early warning criteria,which provides theoretical basis for collapse early warning. In order to facilitate practical appli-cation,a monitoring and warning platform for geological disaster of collapse was built by taking the east and west mine of Chenshan Botanical Garden as an example,and the platform realized real-time import of geological disaster monitoring data and automatic warning function.
