本研究在實驗室進行渠床堆積體因滲流作用，顆粒堆積體破壞發展成顆粒流之渠道實驗，使用高速攝影機進行影像分析，了解堆積體受上游入流水的影響，堆積體內部滲流作用下的破壞歷程、洪峰流量、顆粒流的運動特性及撞擊擋板的受力分析。採用超聲波設備量測顆粒流通過各斷面的發展歷程及顆粒流速度，比較上游供水量及坡度在斷面發展歷程及速度的影響。自行組裝電阻式應變感應器量測擋板受力，與動壓、靜壓模型理論比較。
顆粒流波峰高度因坡度、供水量、底床有無堆積而有所不同，顆粒流波峰在固定底床條件下高度呈現衰減趨勢，而在堆積底床條件下顆粒流波峰高度發生捲增現象，高度呈現增加趨勢。顆粒流撞擊垂直擋板的高度可以知道擋板總受力有明顯的峰值發生，顯示撞擊高度與應力的形成方式有一定的相關性。

The debris flows transformed from the collapse a granular pile by the action of upstream runoff and seepage was experimentally investigated in an inclined flume in this study. The mobilization process of the granular particles are observed by employing image analysis and ultrasonic sensors, while the impact force was measured by the load cell. The measured impact forces were compared with the dynamic pressure model and hydrostatic pressure model. The surge height of granular flows depends on the channel slope, seepage discharge and the bed deposition. For a rigid bed, the surge height decays with distance. While the surge height grows with distance for the cases of the granular pile on a loose bed. An obvious peak value of impact force upon the vertical wall was observed once the granular surge reached the wall, while subsequent increase of the force was related to the water pressure due to inundation .
