| dc.description.abstract | 本研究主要應用地電阻影像剖面法，於梨山地滑區域及台北市北投區水磨坑溪、台北縣金山鄉重和村、南投陳有蘭溪及宜蘭茲那谷溪等土石流堆積區進行地電阻施測，並配合研究區域中的露頭電阻及鑽孔資料進行比對，來探討梨山地滑與土石流的特徵與電阻率之相對關係。
研究成果顯示，梨山地滑區的規模大、滑動深度深、滑動分區多、地下水脈複雜，經由縱向及橫向交錯的佈置，可以瞭解地滑區下方的崩積土與風化板岩分佈、阻水層位置、地下水流向情形。由電阻剖面顯示B13滑動體，是屬於滑動較活躍的區域。由梨山地滑區所量測電阻率最高僅為300～400 Ω-m，表示測區探測深度內板岩基盤之裂隙發達，並為含水溼潤之現象；土石流堆積厚度與下方岩盤電阻率確實有明顯的差異。在近地表處的高電阻率區域，即土石濃度較高的部分，其堆積深度有較深的情形。 | zh_TW |
| dc.description.abstract | The aim of this study is to investigate the resistivity responses in the Lisan landslide area and debris flow areas (i.e., Sei-Mo-Kong stream Beitou District of Taipei City, Jung-He village of Jinshan Township of Taipei county, Chen-Yu-Lan River of Nantou County and Tz-Na-Gu River of Yilan County etc.) using the resistivity image profiling (RIP) method. Referred to the resistivity of outcrops and drilling data, the resistivity characteristics of the layers both in Lisan landslide and debris flow sites can be recognized.
Based on the RIP data collected from survey lines parallel and perpendicular to the land slope of Lisan site, the landslide phenomenon mainly develops in the contact surface between basement rocks and the overlaid loose colluvial soils or weak slate formations. The potential sliding layer is at shallow depth. The activity of slipping body numbered B13 has greater potential. The flow pattern of groundwater is dissimilar from the topographic features. The highest resistivity zones at the shallow depth range from 300 to 400 Ω-m and indicate that the slate bedrock is rich of fractures and has greater water content.
The RIP data collected at the debris flow area indicates that an obvious difference of resistivity can be recognized between the deposition of debris flow and the bed rock underneath. High resistivity zones are found at shallow depths, which have greater density of debris and greater thickness than other place. | en_US |
