摘要

傾斜管為坡地監測經常使用之儀器之一，但因裝設的過程或地層滑移變動的複雜性，觀測的結果多不理想，甚至影響到後續的判釋工作。本文主要以傾斜管變位探討山棕寮地區大規模地滑之變化情形，並以相關建議之基準值進行研判，以釐清山棕寮地滑主要位移情況及其分布區，並佐以現場鑽探及地下水位調查之結果綜合分析研判，提出地滑整治優先處理之區域，降低地滑再次移動之影響。分析結果顯示，地滑區域之上半段相對位移較明顯，且地下水位也以頭部較高，建議於此區設置集水井及橫向排水，降低地下水之影響，並持續觀測其穩定性。

Inclined tube was one of the landslide frequently monitoring instruments, but due to the installs process or stratum sliding change complexity, many observation result were not ideal, even affects the following interpretation work. This paper mainly uses inclined tube to dislodge and discusses the change of large-scale landslide situation in Shan-Zong-Liao area, to carry on the evaluation by the suggestion value of related datum and clearly define main displacement situation and distribution area in Shan-Zong-Liao landslide. Assisting by the scene drilling and the groundwater investigation to generalize analysis evaluation to propose region of the landslide improvement priority facility and reduce influence of once more migration. Analysis result show, the relative displacement is obvious above the landslide region and the groundwater is also high by the forehead. Suggestion establishment sunk basin and cross drainage in this area to reduces the groundwater influence and observe its stability continually.
