Ta Zi Ping Landslide Displacement Real-time Monitoring And Data Analysis

After the 2008 Wenchuan earthquake, red the residents of Hongse village, Hongkou town Dujiangyan city are threatened by Ta Zi Ping landslide.Due to the sudden and uncertain landslide formation, the need of monitoring and early warning of high precision, real-time, dynamic. Need the system reliable processing and management of monitoring data, and provide the correct results.In order to predict the deformation trend of the landslide.GPS-GPRS monitoring and early warning technology Consists by real-time GPS positioning technology and GPRS remote data transmission technology. GPS positioning technology has the characteristics of all-weather, all time, high accuracy, quick positioning. GPRS transmission technology is not subject to regional and distance constraints, real-time and dynamic data transmission. HCmonitor as the difference calculating software.It is real-time, dynamic, automatic data processing and storage of data, and timely dissemination of early warning information.GPS-GPRS and HCmonitor technology combined with solar power technology, DNS technology and GIS management technology, the establishment of the tower landslide surface displacement monitoring and early warning system.Based on the stability analysis of the Base station, and analysis of the monitoring station coordinates data accuracy.On this basis by using 3 kinds of methods to analyze the data. Respectively, by comparison of monitoring data, the deformation trend of the landslide, and the horizontal displacement of the spatial statistics.From the aspects of analysis of deformation characteristics of the landslide, and get high precision results.The analysis results show that, the landslide will be in a steady state for a long period of time.Through the stability test to verify the correctness of the analysis results, and prove that the analysis of the present state of the judgment of the landslide model and the feasibility of future prediction of the data.
