Influence of Stratigraphic Variability and Ground Motion Properties on the Effectiveness of Dense Granular Columns as Liquefaction Mitigation for Structures
(American Society of Civil Engineers, 2025)The current practice of designing dense granular columns (DGCs) to mitigate liquefaction is based on assumptions of uniformly layered deposits of relatively shallow, saturated, continuous, clean sand with no structure. As ... -
Characterization of the Correlative Relationship between PCPT Radial and In Situ Horizontal Coefficients of Consolidation
(American Society of Civil Engineers, 2025)The coefficient of radial consolidation (cr) obtained from the piezocone penetration test (PCPT) differs in value from that of horizontal consolidation (ch) that is commonly adopted in the design of prefabricated vertical ... -
Stimulation of Unconsolidated Reservoirs: Sensitivity Analysis of Petrophysics Using Experimental and Numerical Methods
(American Society of Civil Engineers, 2025)Throughout the lifespan of oil fields, stimulation techniques play a crucial role in altering the petrophysical properties of the reservoir sections, hence impacting their productivity. Several studies have highlighted the ... -
Key Findings on the Role of Corner Frequency in Site-Based Stochastic Ground Motion Models
(American Society of Civil Engineers, 2025)Site-based stochastic ground motion models (GMMs) are essential for representing seismic input in uncertainty quantification methods for earthquake engineering. A key element controlling the long-period spectral behavior ... -
Factors Affecting Liquefaction Triggering of Granular Soils in Laboratory Testing
(American Society of Civil Engineers, 2025)In practice, liquefaction assessment is driven by earthquake case histories, but the case-history database is limited and there are important gaps in the information available. As a result, laboratory tests have continued ... -
Prediction of Soil Freezing Curve from Adsorption-Induced and Capillarity-Induced Water Pressure
(American Society of Civil Engineers, 2025)The soil freezing curve (SFC) is the constitutive relationship between the unfrozen liquid water content of soil and temperature in subzero (<0°C) environments. The water-to-ice phase transition is governed by the ... -
Mechanical Behavior of a Hardened Oil–Silica Sand Composite
(American Society of Civil Engineers, 2025)To evaluate the mechanical behavior of a potential soil stabilizer (a hardening tung oil) with a coarse silica sand, the strength characteristics at both peak and critical state and the stress–dilatancy relationship were ... -
Influence of Loading History on the Creep Behavior of Rockfill under Confined Oedometric Conditions
(American Society of Civil Engineers, 2025)Creep, once considered an inherent characteristic of granular materials, is primarily governed by time and the current stress state. However, recent studies indicate that creep development is also influenced by the loading ... -
Effect of Nano-CaCO3 and Nanosilica on the Strength and Deformation Behavior of Black Cotton Soil
(American Society of Civil Engineers, 2025)This study investigated the impact of optimum dosages of nano-calcium carbonate (nano-CaCO3) and nanosilica on the engineering behavior of black cotton soil. The desired percentage of nano-addition, 2%, for both nanomaterials, ... -
