Study on the Calculation Method of Water Inflow Velocity of Loose Rock Landslide

Landslide surges pose a serious threat to the ecological environment and human life safety. Based on rock structure mechanics water sediment dynamics, considering additional resistance caused by interference of loose landslide particles flow structure, this paper deduces calculation formula loose-rock when entering water. It modifies velocity (ASCE) recommended American Society Civil Engineers. The acceleration bulk-rock landslides are obtained, determination method main parameters in is given. data Xintan into Yangtze River, rationality results ASCE compared analyzed. shows that calculates average movement land, there will be noticeable deviation from actual situation it used calculate entry landslide. given more practical can
