dc.description.abstract | By an onsite investigation, the largest
debris flow in Taiwan’s history is analyzed in
this paper. A heavy rainfall of 1748 mm/day
occurred during typhoon Herb in the Hoser
area at the end of July 1996. Aerial photo
assessment and observations of geological
and geomorphological features have
contributed to our understanding of this
massive destruction. Mechanisms of the
hazardous debris flow are explored and
discussed.
Data revealed that the rock
discontinuities were a major factor in the
voluminous loose materials in the debris
flows. The heavy and rapid rainfall instantly
transported massive amounts of debris flow
materials into the center and then quickly
funneled them to the lower parts of gullies.
The heavy slurry became an effective cutting
device to erode the sidewalls and move large
quantities of the debris materials to the end
of the gullies. | en |
dc.description.abstract | 本文以現場調查之觀點來分析台灣
史上最大的土石流災害。1996 年7 月底,
賀伯颱風給和社地區帶來了1748mm 的日
降雨量。從航照圖的分析以及其他地質、
地貌表徵的調查工作有助於我們收集大量
的資料對於破壞現象的了解,而土石流災
害的機制也一併在現地調查工作中討論。
從現地調查的資料中顯示,岩石不
連續面的崩解,突然使得溝谷兩旁之地質
材料堆積於溝谷中,是造成本次災害的主
因。而大量及迅速的降雨,將這些堆積於
溝谷中的地質材料不停的運往下游。這些
瞬間形成的土石流不僅往下流動,也一面
對溝谷兩側的谷壁產生淘挖、沖蝕的現
象,並同時將兩側崩坍之土石匯聚於溝谷
中,一併往下面流動至溝谷底部。 | zh_TW |
