【摘要】：2008年汶川大地震后,都江堰虹口鄉(xiāng)紅色村的居民長期受到塔子坪滑坡的威脅。由于滑坡災(zāi)害形成的突發(fā)性和不確定性,因此需要高精度和實時動態(tài)的監(jiān)測預(yù)警;并需要可靠的數(shù)據(jù)處理、管理、分析,從而預(yù)判滑坡體的變形趨勢。GPS-GPRS監(jiān)測預(yù)警技術(shù)因其全天候、全時段、精度高、定位快、無需通視的GPS實時定位技術(shù)和無地域無距離限制實時動態(tài)的GPRS遠程數(shù)據(jù)傳輸技術(shù),現(xiàn)已廣泛應(yīng)用于滑坡表層位移監(jiān)測;基于HCmonitor的實時差分解算實現(xiàn)了監(jiān)測數(shù)據(jù)實時動態(tài)的自動化處理、儲存和預(yù)警信息發(fā)布;再結(jié)合太陽能供電、DNS動態(tài)域名解析以及GIS空間數(shù)據(jù)管理等技術(shù),建立了較為完善的塔子坪滑坡表層位移監(jiān)測預(yù)警系統(tǒng)。通過對基準(zhǔn)站的穩(wěn)定性分析以及監(jiān)測站采集的坐標(biāo)數(shù)據(jù)的精度分析,確保了該監(jiān)測系統(tǒng)的數(shù)據(jù)精度。在此基礎(chǔ)通過采用監(jiān)測數(shù)據(jù)的分期比對、滑坡體的變形趨勢曲線圖以及水平位移的空間統(tǒng)計3種分析方法,多方位、高精度的分析該滑坡體變形規(guī)律,分析結(jié)果表明塔子坪滑坡體已經(jīng)處于并將長期處于穩(wěn)定狀態(tài)。通過滑坡穩(wěn)定性檢驗驗證了分析結(jié)果的正確性,同時證明了該數(shù)據(jù)分析模型對滑坡體狀態(tài)的現(xiàn)階段判斷和未來預(yù)測預(yù)報的可行性。
[Abstract]:After the 2008 Wenchuan earthquake, residents of Hongkou Village in Dujiangyan were threatened by the Taziping landslide for a long time. Because of the sudden occurrence and uncertainty of landslide disaster, high precision and real-time dynamic monitoring and early warning are needed. And it needs reliable data processing, management and analysis, so as to predict the deformation trend of landslide body. GPS-GPRS monitoring and early warning technology, because of its all-weather, all-time, high precision, fast positioning, The GPS real-time positioning technology without general view and the GPRS remote data transmission technology without region and distance restriction are widely used in landslide surface displacement monitoring. The real-time differential decomposition algorithm based on HCmonitor realizes the real-time and dynamic automatic processing, storage and early warning information release of monitoring data. Combined with solar power supply, DNS dynamic domain name analysis and GIS spatial data management technology, a relatively perfect surface displacement monitoring and warning system of Taziping landslide is established. By analyzing the stability of the datum station and the precision of coordinate data collected by the monitoring station, the data accuracy of the monitoring system is ensured. On this basis, the deformation law of the landslide body is analyzed by using three kinds of analysis methods, such as the phase comparison of the monitoring data, the deformation trend curve of the landslide body and the spatial statistics of the horizontal displacement, so that the deformation law of the landslide body can be analyzed in various directions and with high precision. The results show that the Taziping landslide has been and will be in a stable state for a long time. The correctness of the analysis results is verified by the landslide stability test, and the feasibility of the data analysis model for the present stage judgment and future prediction of the landslide state is proved.
