Numerical investigation on debris flow impact using a flow-structure coupled SPH method
Debris flow is a global geological disaster in which water-laden masses of soil and fragmented rock rush down mountainsides,funnel into stream channels,entrain objects in their paths,and form thick,muddy deposits on valley floors.It could move faster than the landslides and tend to affect areas at a much greater distance from the source of hazard.Therefore the occurrence of debris flow is very destructive.The 2008 Wenchuan earthquake triggered numerous landslides and left a large amount of loose material on the steep slopes and in the gullies.As a consequence of heavy rainstorms,catastrophic debris flows have been triggered,resulting in more than 2,000 deaths/missing persons,and destroying numerous houses,bridges,and traffic facilities in the earthquake-affected areas (Tang et al.2009,2012; Xu 2010; Xu et al.2012).
