الوصف: 邊坡穩定分析是對地滑邊坡安全性的決策依據,由安全係數的大小及破壞面的情況可對邊坡的穩定情況有基本的瞭解。應用地理資訊系統的資料庫功能,以及空間分析的強大功能,對梨山的地質鑽探資料進行整理統合,再結合邊坡穩定分析程式,除對梨山地滑邊坡進行反算分析外;另將邊坡穩定分析結果,架構即時分析安全係數之專家資料系統。 本研究以梨山為例分成五個部份探討。1.地質分層:對鑽井的岩心資料建檔後,加以分成崩積土層、準滑動層、不動層,應用各種不同的克立金空間內插模式進而推求整個梨山地區的地質分層系統;2.弱面的判識:由梨山地區自動監測資料與分析所得的剖面進行可能滑動面的研判;3.地質參數之決定:將臨界的剖面進行反算,以得到梨山地區最佳地質參數;4.迴歸分析:由假設自動監測站之地下水位的變化,進行邊坡穩定分析,以求得加地下水位變化與FS的關係式;5.專家系統之建立:將所有的分析結果加以整合,將即時之水位高程資料以安全係數反應,作供決策上的參考。本研究將以自動監測及TDR觀測資料配合地質鑽探與分析結果對梨山地區可能滑動面進行研判,並將訂定梨山管理準則的地下水位基準值。 本研究建構了梨山地區邊坡穩定的即時分析系統,並成功的驗證了應用地理資訊系統與邊坡穩定結合應用的可行性。專家系統以即時的地下水位即時反映出安全係數不但可立刻得知現正的剖面情況,對梨山地滑地的管理決策上亦提供了支援的能力。 ; Slope stability analysis is an important judgment in regard to remedial work.The basic condition of the slope can be evaluated according to it's factor of safety and the position of failure surface. Organize and analyze the geological data of Lisan Area by Geographic information system(GIS) which is used for data management and spatial analysis by combining the GIS with the SLIDE(an 2-D slope stability program).The conclusion of analyzing Lisan Land slide area, establish the expert system which analyze the FS immediately. There are five parts to be discussed in regard to risk analysis of Lisan Area : First, saperate geological layers distributions into three parts using drilling data. The spatial interpolation model developed in this research is provided to predict the system of geological layers. Second, determine the possible sliding surfaces by the data of auto-monitoring stations and the profile. Third, decide the geological strength parameters by back analyzing the critical slope in Lisan land slide area. Fourth, calculate the regression function , using the assumed ground water level and the according FS. Fifth, combine all of the conclusion to establish the real-time system which snap the water level data of Lisan auto-monitoring station and calculate the according FS in real time. Using the data of auto-monitoring station and TDR, the possible slide surface could be determined, the gate value of water level could also be ...
