Analysis on Turbulent Debris Flow’s Movement Energy in Circulation Area
The gully shapes of Debris flow are generally classified into formation area, circulation area and accumulation area, these three sections . That wide formation region, narrow circulation area and wide, slow deposition area is the typical geomorphology of fluctuant type gully erosion and deposition Debris flow.The key area of the debris flow’s movement and development is the circulation area. Based on analysis the turbulent debris flow’s moving characteristic in circulation area with the solid-liquid two-phase flow’s standpoint, energy equation and the formulation of impact force for the block structure of turbulent debris flow in circulation area are deduced. It affords important idea for the further investigation about the debris flow’s protection engineering, but some parameter in the formulation need fit from the model examination.
