摘要

台灣地區位處歐亞板塊與菲律賓海板塊交界處，坡地面積佔70%以上，加上地形陡峭、地質年代輕、地質構造複雜、岩性脆弱、降雨量多，以及人為開發不當等因素，經常造成各類型坡地災害。邊坡穩定工法常繫於對工址基地及周邊環境基本資料的瞭解，其中以地質因素最為重要。本文將就邊坡穩定工法所需之地質調查原則及方法加以介紹，期能對於工法的選擇、設計、施工及維護管理有所助益。

Taiwan is located at the convergent boundary of Euroasian plate and the Philippine Sea plate. 70% of Taiwan area is mountainous. Various hazards are mainly caused by steep topography, complicated folding and faulting geology, heavy rainfalls and inappropriate development of slope.The feasibility of slope protection measures should consider inherent factors of site, especially geological factors and surrounding environments. It is expected that the geological investigation principles and methods described in this paper would be helpful for engineers in gaining the ability of protection method selection, design, construction and maintenance.
