    • 文本主要以實驗的方式來觀測兩種不同擋水閘門之潰壩情形，分別是抽取式全潰壩型式與前傾潰倒式部分潰壩型式。前傾潰倒式閘門係根據前人文獻所統計之堰塞湖潰壩情況，及許多現地實際潰壩之比例來設計，而全潰壩與部分潰壩將會個別討論之。
    而為了解全潰壩後的波頭的內部流場演變過程，利用高速攝影機捉取瞬時流況之照片，並討論在水深20與30公分下、水深比0、0.1、0.2與0.3狀況下內部流場變化的情形。利用互相關分析方法，分析其波頭瞬時流速、縱向速度分布、臨界流況。
    部分潰壩實驗為潰倒式閘門設計，更貼近實際上發生的狀況。並且改善以前閘門潰倒時無法完全展開，造成對水平速度的影響，亦改進閘門潰口兩旁的設計，使其三維現象消失。而部分潰壩試驗條件有潰倒比1/10、1/5、1/3三種。而在本實驗中，發現同潰倒比時，初始流速十分接近，最大流速約為0.8√gh。

    Using the pull-type gate (full dam-break) and the collapse-type gate (partial dam-break) to observe two different situations of dam-break flow, collapse-type gate statistics literatures under the previous collapse of the barrier lake dam situation, and in many proportion to the actual dam-break design.
    Measuring the bore velocity and the jet by high speed camera witch can capture 1000 photographs in one second. Upstream water depth is 30cm and 40cm of full dam-break conditions, and the ratio of water depth is 0,0.1,0.2,and0.3,the zero ratio is the condition of dry-bed case.
    The collapse-type gate (partial dam-break) has been designed much better than which one we used before. We can completely open up the collapse-type. (it means the gate can open up 180 degree) and reducing three-dimensional phenomenon.
    The collapse ratio of partial dam-break is 1 / 10, 1 / 5, 1 / 3. In the same ratio, we find that the initial speed is propinquity. And the max initial speed is 0.8√gh.
