Micro-CT Scanning to Examine Soil Clogging Behavior of Natural Fiber Drains
Publisher: American Society of Civil Engineers
Abstract: The use of jute and coir fibers as natural fiber drains to facilitate drainage and soft soil stabilization has been proposed for decades. However, their uncertain hydraulic behavior has often hampered their wider application ...
A Coupled CFD–DEM Approach to Examine the Hydraulic Critical State of Soil under Increasing Hydraulic Gradient
Publisher: ASCE
Abstract: Increasing hydraulic gradients and associated seepage in a soil foundation accompanied by a reduction in effective stress, degradation of soil stiffness, and diminished internal stability contribute to adverse conditions ...
Simulating Subgrade Soil Fluidization Using LBM-DEM Coupling
Publisher: ASCE
Abstract: The loss of effective stress due to increasing excess pore pressure that results in the upward migration of soil particles, that is, subgrade fluidization and mud pumping, has been a critical issue for railways over many ...
Performance of Composite PVD–SC Column Foundation under Embankment through Plane-Strain Numerical Analysis
Publisher: ASCE
Abstract: The combination of soil–cement (SC) columns and prefabricated vertical drains (PVDs) has indicated great success in improving ground stabilization in recent years; however, there is a lack of proper plane-strain numerical ...
