摘要

在崩塌地層滑動面與移動量之調查時，常於鑽孔中埋入具十字凹槽之測管後再定期以裝有傾斜感應器之儀器檢測測管所產生之傾度變化，並換算為地層之位移量，但因裝設的過程或地層崩滑變動的複雜性，觀測的結果多有不理想者，影響到後續的判釋工作。本文主要是研製分層懸垂的測管埋入鑽孔中，運用工業級內視鏡觀察懸垂的變動情形而換算為地層傾度變化。分析結果顯示，內視鏡觀測比傳統傾度管觀測更能有效的判定崩塌滑動面及地層位移量，但所研製儀器的元件之耐久性與管壁抗壓性仍有改善的空間。

At present the monitoring method of landslide strata survey and sliding displacement, usually put the special pipe with cruciform recess into the boring hole, and regular uses inclination sensor to investigate the movement data of different depths in this pipe to measure the displacement in the stratum and judge the sliding surface area. Unfortunately, this innovative research lack of experience and due to the problem of installation process or stratum sliding change complexity, many observation results were not ideal, even affects the following interpretation work. This paper mainly compared investigation data of inclination tube and laparoscope image to discuss the change of landslide situation. The results of analyze show that laparoscope image is valid to determine landslide surface and sliding displacement but the problems of component durability and tube resistance still need to improve.
