中文摘要 | 坍方地質調查經常是山坡地規劃利用時的第一個步驟。本文介紹台灣中南部一個 坡地的坍方地質調查實例,內容包括調查過程、地層分層依據、岩石分類命名依據、基地地 質圖、地質剖面圖、坍方辨識依據、坍方模式及特性、以及坍方分佈圖等,文中並且針對地 質資料的可靠度進度進行探討,強調事實資料 (fact data) 及解釋性資料 ( interpretation data ) 分列清楚,在避免地資料的誤導或誤用上,非常重要,在國土的開 發、建設及保全上,有一定的作用。坍方調查結果顯示,基地內存在一種地滑型坍方,發生 在坡度僅 10 度左右的平緩順向坡面上 (dipslope),該種坍方無法從現有的航空照片上 ( 比例尺約二萬分之 ) 辨識出來,但活動性高, 在土地利用及災害防治上有其重要性,值得 重視。 |
英文摘要 | Landsliding mapping is always the first step in the process of slopeland development This paper presents a landsslide mapping case in the South-western Taiwan. Investigation process, site geology, and landslide mapping are brienfly described. Geological data reliability is discussed to avoid misleading and misusing. A special type of landslide is recognized in a gentle dip solpe (only 10 degree in dip angle), but can not be discerned from the available airphotographs (with scale of about 1/20,000). These special landslides are quite active. A special type of landslide is recgnized in a gentle dipslope (only 10 degree in dip angel). These special landslides are quite active, but can not be discerned from the available airphotographs (with scale of about 1/20,000). It is important to identify their distributions before any slopeland development. |
