| 中文摘要 | 近年來,土石流在臺灣各地造成嚴重之災害。為了瞭解土石流發生之機制,國內外學者紛紛投入土石流發生模式之研究,其中,又以土石流發生之臨界角模式最多。由於假設條件之不同,各家模式推導結果亦有相當之差異。為瞭解各公式之異同處,本研究整理所蒐集到之土石流發生機制公式,除列出其假設條件和實驗條件外,並將模式轉換成相同參數以進行敏感度分析。在不同之適用條件下,將各發生機制模式依飽和水層與堆積面之相對位置等三種情況,分別進行敏感度分析與比較,得到不同狀況下各模式間之差異。 |
| 英文摘要 | Recently, the occurrence of debris flow results in severe disasters around the Taiwan Island. IN order to explore the triggering mechanism of debris flow, many researchers made their effort on the study of triggering model of debris flow around the world. In which, focus on the critical angle for debris-flow triggering was the majority. Because of the different assumptions, each deriving model has its different performance, respectively. To understand the variety of each model, this study, collecting and listing each assumptions and experimental conditions, carry out the sensitivity test by transferring into the same parameters. Under specified conditions, three kinds of relative status of saturated zone and deposit zone are analyzed and compared by sensitivity test and explore the difference between collecting models. |
