Chinese Abstract

土石流因具有再生性,故爲瞭解其重複發生,而在下游地區造成重複堆積之特性,特藉渠槽試驗以觀測其連續堆積之情形,並驗證理論公式之適用性。本試驗係以三種不同渠槽坡度及三種不同土石流量,在相同土石流規模之條件下,令其重複堆積。由試驗結果得知:相同規模之土石流其重複堆積之長度較之初次堆積之長度並未增加,但卻稍微擴大其堆積面積,而由公式(1)推估重複堆積長度時,會有稍微高估之情形,但並不影響(1)式之適用性。

English Abstract

Debris flow can be regenerated as the soil materials deposit enough in the valley and the rainfall is strong enough. Therefore, the soil materials which contain with coarse and fine granulars, will be carried out and deposit on the low land to form an alluvial fan. As to the progression of alluvial fan which is caused by debris flow, is concerned as an important factor for preventing from the damage of debris flow. Therefore, this paper is going to study the sequent deposition of debris flow in order to know the progression of debris-flow fan. The experiment was conducted with a flume in laboratory. And three different slopes and three different debris-flow discharges were used to observe the sequent deposition with the same scale of debris flow.
