Study Of Remote Monitoring And Prediction Method For Zhenjiang Slope Geological Hazard

In the influence of factors,such as climate change,the geological events and engineering activities increased,geological disaster situation is very serious in our country,and geological disasters will show a high incidence of long-term trend.So,the prevention and control work need to further strengthen in urgently.In this paper,based on zhenjiang slope geological disaster prevention engineering,slope geological disasters remote monitoring and prediction method is study.the main research content are as follows:(1)Zhenjiang area geological environment features,slope geological disasters and human engineering activities on the influence of geological environment are are analyzed and summarized.(2)Applicate the finite element to analysis the rainfall infiltration effect on the slope stability,get the rainfall parameters and soil parameters on the influence of rainfall infiltration law of slope stability,analysis the slope stability with the slope displacement and the horizontal stress relationship,under the rainfall,which get the relations of each parameter and rainfall durative time;According to monitoring data expected results analysis of slope landslide thrust,slope surface displacement and underground water level,the rule of landslide criterion is established.(3)Based on the theory of Internet of things technology,a system of remote monitoring and prediction of slope geological disasters is constructed.Setting automatic sensing monitoring device,data acquisition and sending devices,and uninterrupted power supply device in disasters slope body,then using wireless sensor network,through the monitoring of rainfall and slope position shift,to transmit data to a remote server,by analysis of monitoring and early warning platform for timely release.Multitasking network communication,information management and early warning and prediction of slope stability are realized.(4)A slope located in the west of Zhenjiang martyrs cemetery is researched for the safety problem.In this essay an efficient and energy saving slope monitoring device system is established,which is based on the real-monitoring system of the GNSS technology.The system mainly aims at displacement and rainfall monitoring.The rainfall is measured by tipping bucket rain gauge.With the GPS equipment distributed around the slope,the real-time on-line automatic monitoring system works well.Based on Microsoft Visual C++ network technology and SQL Server 2005 data base,geological disaster remote warning and forecasting system of slope in Zhenjiang martyrs cemetery is independently developed According to the data having been monitored,the system thinks that the slope is still in a safe state.
