The Role of Fabric, Stress History, Mineralogy, and Particle Morphology on the Triaxial Behavior of Nontextbook Geomaterials
(American Society of Civil Engineers, 2024)Soil mechanics traditionally have focused on studying pure clays and clean sands. However, natural soils and other geomaterials usually do not fall into these two classes. Most geomaterials are a complex matrix of fines ... -
Field Evaluation of the Installation and Pullout of Snakeskin-Inspired Anchorage Elements
(American Society of Civil Engineers, 2024)Soil nails and tieback anchors are used extensively for excavation support and slope stabilization; however, their performance can be complicated by limited pullout capacity or installation challenges. This paper presents ... -
DEM Investigation of the Effect of Gradation on the Strength, Dilatancy, and Fabric Evolution of Coarse-Grained Soils
(American Society of Civil Engineers, 2024)Design of geosystems built on coarse-grained soils with broader gradations are typically based on methodologies developed for clean sands without explicit consideration of the effects of gradation, potentially leading to ... -
Mitigating Zinc Leachate from End-of-Life Tire Rubber in Stabilized Clayey Soils
(American Society of Civil Engineers, 2024)End-of-life tire (ELT) rubber has been widely researched to replace aggregates in construction materials such as asphalt concrete and cementitious composites. Although most studies paid attention to its effect on engineering ... -
The Effect of Initial Static Shear Stress on Liquefaction Triggering of Coarse-Grained Materials
(American Society of Civil Engineers, 2024)Soil liquefaction response is significantly affected by soil gradation (particle size, angularity, coefficient of uniformity) and density. However, the literature on the factors affecting liquefaction resistance with initial ... -
DEM Modeling of the Load-Bearing Mechanisms of Rock-Socketed Piles with Soft Interface Materials
(American Society of Civil Engineers, 2024)The load-carrying capacity of rock-socketed piles depends on the shaft resistance at the pile-rock interface which is governed by the interactions between the pile, rock, and soft interface materials (smear or infill). ... -
The Effect of Crusts on the Undrained Vertical Penetration Resistance of Pipelines
(American Society of Civil Engineers, 2024)Accurate prediction of the embedment depth of surface-laid pipelines is fundamental to determine in-service performance, which is closely related to the resistance the seabed provides during pipe-lay. The presence of a ... -
Investigation of the Load-Sharing Mechanisms of Suction Buckets during Vertical Cyclic Loading in Layered Soils
(American Society of Civil Engineers, 2024)Suction bucket jackets have been used as foundations for offshore wind turbines in intermediate water depths where layered soil stratigraphies are often encountered. Although suction installation in layered soils has been ... -
A Unified Model of Cyclic Shear–Volume Coupling and Excess Pore Water Pressure Generation for Sandy Soils under Various Cyclic Loading Patterns
(American Society of Civil Engineers, 2024)Accurate prediction of excess pore water pressure (EPWP) generation in saturated sandy soils remains one of the most challenging issues in sandy site responses to strong earthquakes and extreme marine environments. This ... -
An Alternative Approach to Dynamic Earth Pressure Coefficients to Improve the Seismic Limit State Design of Earth-Retaining Structures
(American Society of Civil Engineers, 2024)Dynamic earth pressure coefficients are widely used in the seismic engineering design of earth-retaining structures. Nevertheless, there remains confusion about their validity, with past studies conflictingly arguing the ... -
A Comprehensive Optimization Study of Microbially Induced Carbonate Precipitation for Soil Strength Enhancement: Impact of Biochemical and Environmental Factors
