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
(American Society of Civil Engineers, 2025)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 ... -
Theoretical and Experimental Study on Elastic–Plastic–Sliding Load Transfer Model for Pile Tip and Pile Side Postgrouting Piles
(American Society of Civil Engineers, 2025)An elastic–plastic–sliding trilinear load transfer model is established for grouted piles. This model summarizes the resistance–displacement relationships at both the side and tip of the pile, describing the transition ... -
Thermodynamic Model for Sand-Incorporating Morphology
(American Society of Civil Engineers, 2025)Particle shape, size, and size distribution (gradation) significantly influence the mechanical response of granular soils. This research introduces a thermodynamic model based on granular thermodynamics theory, validated ... -
Failure of Ring Foundations on Soft Clay Reinforced with an Annular Stone Column
(American Society of Civil Engineers, 2025)The pressure–settlement response of ring foundations placed on soft clay and reinforced with an annular stone column was determined both experimentally and numerically. The mean diameters of the ring footing and the stone ... -
Quartic Polynomial Packing Model for Sand-Fines Mixtures
(American Society of Civil Engineers, 2025)The addition of fines to sand directly changes the void ratio of a sand-fines mixture and thereby leads to a change in its mechanical properties. Numerous packing models have been proposed to capture the variation of limit ... -
