Suffusion of Gap-Graded Soil with Realistically Shaped Coarse Grains: A DEM–DFM Numerical Study
Publisher: American Society of Civil Engineers
Abstract: Suffusion refers to the phenomenon in which fine particles in internal unstable soil are carried by seepage through skeleton pores. It is a type of internal erosion that can lead to major hazards for hydraulic and geotechnical ...
Model Test on Backward Erosion Piping under a K0 Stress State
Publisher: ASCE
Abstract: Piping is a major failure mechanism in both dams and dikes. In this work, we develop a transparent specimen tank that allows a camera to clearly record the piping formation process. In addition, this apparatus is able to ...
DEM-DFM Modeling Suffusion of Granular Soils under Triaxial Compression
Publisher: American Society of Civil Engineers
Abstract: Suffusion of soils is one of the common hazards in geotechnical and ocean engineering. The influence of the stress condition of soils on suffusion, however, remains unexplored in previous studies. In this study, systematical ...
