| dc.description.abstract | 本研究在實驗室內進行不同堆積型態之堆積體，因上游之滲流作用造成堆積體破壞，並轉化為顆粒流之渠道試驗。試驗過程中以高速攝影機進行影像攝影記錄其過程，再以影像分析處理，並探討顆粒堆積體內部因後方水體滲流作用下之破壞歷程、後方水深、顆粒流體運動特性、以及在不同型態之顆粒堆積體因侵蝕堆積床造成顆粒流之捲增效應。顆粒流因堆積型態與供水量、傾斜坡度條件之差異使顆粒流流動型態有所差異。顆粒流之波峰在固定底床條件下高度呈現遞減趨勢，而在堆積底床條件下，因顆粒堆積體在破壞過程中會侵蝕底床，而有捲增效應使土石流整體前鋒呈遞增之趨勢。 | zh_TW |
| dc.description.abstract | In this study, the mobilization process of a deposited plie due to upstream seepage failure was experimentally investigated in a flume. The flow patterns of the granular flows depend on the channel slope, seepage discharge and the bed deposition. For a rigid bed, the surge height decays with distance. For a loose bed, the wet granular flow entrains particles of the bed during the mobilization process, and the surge height grows with distance due to the entrainment effect. | en_US |
