摘要: Flowslides are a frequent type of natural disaster in loess areas and may result the significant loss properties and/or casualties. The Dagou flowslide is typical event area accompanied by sediment entrainment. To analyze mechanisms responsible for flowslides to obtain parameters runout analysis, field investigation was conducted. Specimens were sampled on site carry out laboratory tests, including triaxial test, sieve chemical component analysis. used study employing an energy-based model. An analytical entrainment model adopted calculate after considering physical mechanism process loess. Finally, incorporated into simulate post-failure this case. Energy dissipation due deformation slices considered as it thought be important slide with deformation. simulation results compared measurements, distance, total volume, erosion depth, deposition height at different sections, velocities specific locations. indicate that model, together can capture kinematic characteristics flowslide. Therefore, feasible use predict similar areas. Copyright (c) 2017 John Wiley & Sons, Ltd.
