Stability Analysis of an Undrained Cohesive Slope Consisting of an Embankment and Foundation Soil: Design Charts Involving Limit-State Lines and Failure Mechanisms
(American Society of Civil Engineers, 2025)Abstract Short-term stability of slopes in which embankment material and the foundation layer material have two distinct undrained strengths is a critical concern in geotechnical engineering. In this paper, a novel ... -
Investigation of the Mineral Content and Geomechanical Behaviors of Shale Gas Reservoirs after CO2 Injection Using Rock Physics Modeling
(American Society of Civil Engineers, 2025)Abstract Gas-bearing shale is a desirable option for geological CO2 sequestration while fracturing and enhancing recovery using supercritical CO2. However, owing to the geomechanical nature of gas shale, there is a chance ... -
Thermomechanical Deformation in Functionally Graded Fiber-Reinforced Media through Fractional-Order Strain
(American Society of Civil Engineers, 2025)Abstract This article addresses the modified theory of fractional-order strain, built upon the Lord–Shulman generalized theory of thermoelasticity. A theoretical framework was formulated to explore the influence of fractional ... -
Stress Path and Orientation Effects on Natural Fiber–Reinforced Sand
(American Society of Civil Engineers, 2025)Abstract Triaxial tests were conducted to investigate the effects of stress path and orientation on natural fiber–reinforced sand. Four stress paths were employed, including the conventional triaxial compression (CTC) test, ... -
Calculation of Temporary Roof Pillar Structure Parameters for a Novel Combined Mining Method
(American Society of Civil Engineers, 2025)Abstract To tackle the technical challenges posed by mining steeply inclined thick ore bodies in deep mines, a combined mining method of roof pillar–induced caving and nonpillar sublevel caving was devised. One of the ... -
Estimation of the Relative Density of Near-Surface Sandy Deposits Using a Free Fall Conical Penetrometer
(American Society of Civil Engineers, 2025)Abstract Estimation of the relative density of sands at shallow depths is crucial for various geotechnical engineering applications (e.g., design of shallow foundations, pipelines, and scour). Free fall penetrometers (FFPs) ... -
Progress in the Treatment Technique of Medium- and Low-Compressibility Soil Foundations under High-Speed Railway Subgrade
(American Society of Civil Engineers, 2025)Abstract In the past, medium–low-compressibility soil foundations were reinforced by using pile foundations that penetrated through the layer. In this paper, a large number of indoor and field tests have been conducted to ... -
A Postpeak Strength Model for Geotextile and Textured Geomembrane Interfaces Considering the Degradation of Interlocked Geomembrane Asperities
(American Society of Civil Engineers, 2025)Abstract The postpeak strength reduction between the geotextile and the textured geomembrane interface is accompanied by the degradation of the geomembrane asperities interlocked with geotextile filaments. This paper aims ... -
