The effects of multi-scale particle shape characteristics on the small-strain stiffness granular soils remain controversial. This study revisits this topic using well-calibrated three-dimensional discrete-element simulations incorporating a roughness–embedded contact model and particles realistic shape. Based numerical simulation results, sands magnitude Hardin's equation parameters are systematically investigated, underlying micro-mechanisms also thoroughly explored. Results indicate that...
Groundwater restoration is increasingly common to mitigate groundwater overexploitation, which proves effective in resolving urban water scarcity and regional unsustainable development. China's South-to-North Water Diversion Project one of the largest transfer projects restore resolve shortage Beijing. However, how rapidly restored this magnitude changes seismic stability largely unknown. Here, we explore relation between elevated table ground liquefaction based on case Beijing under impact...
In an effort to study undrained post-liquefaction shear deformation of sand, the discrete element method (DEM) is adopted conduct cyclic biaxial compression simulations on granular assemblies consisting 2D circular particles. The are able successfully reproduce generation and eventual saturation strain through series liquefaction states that material experiences during loading after initial liquefaction. DEM with different deviatoric stress amplitudes mean effective stresses samples void...
Underground structures in liquefiable ground are prone to severe earthquake damage, and the seismic responses of such underground can be affected by nearby superstructures. Two centrifuge shaking table tests on a precast structure with without superstructure above it mildly inclined were designed conducted this study. The response was analyzed terms its acceleration, deformation, internal force, waterproof performance. influence response, including deformations forces, investigated comparing...
Carbon nanotube/graphene nanoplatelet (MWCNT/GNP) hybrid membranes with lower liquid permeability and better barrier effect compared to MWCNT were successfully synthesized by vacuum filtering. Their morphologies, water permeability, pore structures characterized a scanning electron microscope (SEM) nitrogen adsorption isotherms. Furthermore, MWCNT/GNP used improve the flame retardancy of carbon fiber reinforced polymer (CFRP) composites, influence weight percentage GNPs on was systematically...
