RISBond–Slip Behavior of Concrete Pile–Cemented Soil Interface Considering Thermal–Temporal Effect: Experimental Study and Constitutive Modeling Based on Disturbed State Concept
Publisher: American Society of Civil Engineers
Abstract: The bond–slip behavior of concrete pile–cemented soil interface is crucial for load transfer analysis of stiffened deep cement mixing piles, which is greatly influenced by ground temperature and age during long-term curing. ...
Numerical Study of the Failure Process of Stone Column Groups in Soft Soil in Response to Rigid Loading Based on the DEM-FDM Coupled Model
Publisher: American Society of Civil Engineers
Abstract: Compared with isolated stone columns, a group of stone columns exhibits a much more complicated failure mechanism because of the complicated interactions between the respective columns and the surrounding soil under various ...
A Generalized Load-Transfer Modeling Framework for Tensioned Anchors Integrating Adhesion–Friction-Based Interface Model
Publisher: ASCE
Abstract: The load-transfer mechanism of tensioned anchors is primarily concerned with in-service performance, which depends on the bond–slip behavior of anchoring interface. Because the interface bond–slip behavior is conventionally ...

3D DEM-FDM Coupled Analysis of the Behavior of an Isolated Geogrid-Encased Stone Column under Axial Loading
Publisher: ASCE
Abstract: The axial loading test on a geogrid-encased stone column has been simulated using 3D numerical model in the proposed study. The stone column was modeled using the discrete element method (DEM), and the geogrid was modeled ...
