![]() We have found that numerical modeling can capture the fundamental dynamic behavior of these flow-like landslides and produce preliminary results for hazard assessment and site selection for reconstruction in earthquake-prone areas.īui HH, Fukagawa R, Sako K, Ohno S (2008) Lagrangian meshfree particles method (SPH) for large deformation and failure flows of geomaterial using elastic–plastic soil constitutive model. All simulations show good agreement with characteristics of flow-like landslides observed in the field. Run-out analyses of the Tangjiashan, Wangjiayan, and Donghekou landslides are conducted by the application of SPH models to real flow-like landslides. Then, run-out analyses are performed for flow-like landslides triggered by the Ms 8.0 Wenchuan earthquake that occurred on in Sichuan Province, China. At first, two benchmark problems of dam break and granular flow are simulated and verified to evaluate the accuracy of the SPH model. Compared with conventional methods, the proposed SPH modeling technique is the combination of a Bingham flow model and Navier–Stokes equations in the framework of computational fluid dynamics. In this paper, we use smoothed-particle hydrodynamics (SPH) for the run-out analysis of flow-like landslides. ![]() ![]() However, studying such phenomena with traditional simulation methods is made difficult by their complex fluidization characteristics. Flow-like landslides have caused significant damage and casualties worldwide. ![]()
