Abstract This work presents an improved soil‒water coupling model to simulate landslide‐generated impulse waves (LGIWs) in a unified smoothed particle hydrodynamics (SPH) framework, where both water flow and landslide motions are modeled by SPH using interface technique. Graphics processing unit technology based on open‐source platform DualSPHysics is chosen employ the dynamics achieve capability of large‐scale simulation high‐resolution modeling for three‐dimensional LGIW problems. A...
In recent years, the escalation of climate change has led to a rise in frequency icebergs calving into ocean. These iceberg calving-generated waves (ICGWs) present significant hazard passing vessels and coastal infrastructure. The Eqip Sermia ICGWs event possibly represented most comprehensive record an date. However, survey data are limited due challenges field observations. For instance, three-dimensional shape remains unknown, with only its cross section being discernible. To investigate...
Small-scale model tests have been used widely to examine the behavior of slopes. When all similarity principles are conformed, test results can be translated behaviors slopes in prototype. However, when cannot fully need interpreted. The interpretation stability from small-scale under non-conformity conditions that prototype is investigated, considering various slope scales and soil properties, undertaken through finite element (FE) method conducted by ABAQUS package. Prior conducting...
Mixed fluid–particle flows are commonly found in nature and exhibit complex particle–particle particle–fluid interactions. In this paper, a typical small-scale case of immersed granular collapse under the viscous regime is numerically investigated using computational fluid dynamics coupled with discrete element method (CFD-DEM), which provide particle-scale information collapse. The input parameters for CFD-DEM model carefully calibrated from experimental results, simulation results achieve...
Various soil-rock mixed landslides occur in the natural environment. Carried along slide, boulders will eventually come to rest. The origin of boulder motion provides crucial constraints for inferring geological events. To overcome challenges posed by limited visibility within and subsequent difficulty observing motion, we propose a novel device measure three-axis acceleration angular velocity using Inertial Measurement Unit (IMU) technology. By comparing with traditional high-speed camera,...
Although rainfall is rare on the Loess Plateau of western China, landslides occur frequently there in rainy season. Surveys report that landslide hazards always follow heavy rains. In this study, a seepage-stress coupling model for induced used to examine an actual disastrous event Yulin by end July, 2017. The effects duration, intensity and soil weakening slope stability are studied detail. results illustrate safety factor drops sharply at first then gradually declining below 1.05 during...
Roll waves are frequently observed in the spillway chutes of hydropower stations, flood discharge channels, and diversion canals. In order to understand physical characteristics roll detail, a full two-dimensional numerical model based on Reynolds-averaged Navier-Stokes equation with renormalized group k-ε turbulence volume fluid technique is established simulate evolution wave. A series periodic generated by different combinations slopes discharges successfully simulated, which compares...
Due to a purely repulsive conservative interaction adopted in the traditional dissipative particle dynamics, vapor-liquid coexistence phenomena or fluid flows with free surfaces could not be simulated. In present study recently proposed combination of short-range and long-range attractive for DPD was investigated explore its ability simulating surfaces. With this modified interaction, steady interface obtained simulation, stress distribution across region also discussed, which were found...
