滲流作用引發土石流之試驗

Debris Flows Induced by Seepage

摘要


本研究採用簡化之有限邊坡土體並於土體上游面供水,進行室內水槽試驗,以探討滲流作用引發邊坡破壞與破壞後崩落土石之行為機制。由試驗獲得初步結果如下: 1.土體所受滲流力愈大或土體內水位愈高時,土體內破壞面坡度愈小。 2.土體破壞面坡度為影響邊坡破壞後崩落土石之流動與否之一因子。

For researching slope failure induced by seepage and the movement of destructed soil mass, we conducted a flume experiment with a finite slope of soil body. The results were obtained as following: 1. In the soil body, the higher seepage force or the higher water level induced slope failure with the lower steepness of failure surfaces. 2. The steepness of failure surface was probably an affecting factor to transform soil body from sliding into flowing.
