Abstract

Debris flows are the flows of the mixture of soil，water and air，having property between sandy floods (sediment-laden flows) and landslides. Even though the debris flows are different from the sandy floods or landslides，and they have some-degrees similarity in the view of rheological properties. The sediment concentration in debris flow increases with the increase of sediment entrained in the flow. Debris flow physical properties and structure would significantly changed as the sediment contents in the flow arrives or exceeds 380 kg/m3. It is one of the most basic and important physical properties of debris flows. Debris flow at Jiangjia Ravine is famous in the world for occurrence frequently，scope largeness，severity disasters.
