Macroscopic Embodiment of Stress–Strain Behavior of Backfill Soil on the Displacement-Dependent Earth Pressure Curve
(American Society of Civil Engineers, 2018)Treating the soil within the failure zone behind the wall as the specimen in a simple shear box, and the soil transition from initial to limit states as the shearing process of soil specimen, a geometrical model was proposed ... -

Seismic Active Thrust on Rigid Retaining Wall Using Strain Dependent Dynamic Properties
(American Society of Civil Engineers, 2018)An analytical model is proposed for the evaluation of seismic active thrust on retaining wall resting on sandy soil. Foundation and backfill soil is idealized as Kelvin-Voigt solid. The governing differential equation of ... -
Use of Viscoelastic Continuum Damage Theory to Correlate Fatigue Resistance of Asphalt Binders and Mixtures
(American Society of Civil Engineers, 2018)The objectives of this study were to evaluate the fatigue resistance of asphalt binders in relation to their composition and establish the correlation of the fatigue property of asphalt binders with that of mixtures using ... -
Prediction of Bearing Capacity of Ring Foundation on Dense Sand with Regard to Stress Level Effect
(American Society of Civil Engineers, 2018)This paper uses finite-element formulation of the lower bound theorem to determine the bearing capacity of ring foundations on dense sand. The results are validated with the plasticity solutions, numerical analyses, ... -
Stability Analyses of Initial Collapse and Earthquake-Induced Secondary Failure Using Discretization-Based Kinematic Analysis
(American Society of Civil Engineers, 2018)A stability analysis of slopes is presented using the discretization-based kinematic analysis. By generating a discretized failure mechanism satisfying the kinematic admissibility condition with the use of a discretization ... -
Centrifuge Model Test Study on Failure Behavior of Soil Slopes Overlying the Bedrock
(American Society of Civil Engineers, 2018)A number of landslides occurred in the soil slopes deposited on the bedrock. The bedrock significantly influenced the failure behavior of the overlying slope, which should be reasonably captured in the slope stability ... -
High Frequency Acoustic Emissions Observed during Model Pile Penetration in Sand and Implications for Particle Breakage Behavior
(American Society of Civil Engineers, 2018)Particle breakage has a significant impact on the mechanical properties of soils and has drawn continuous concerns among researchers. This study aims to deepen the current understanding on the particle breakage phenomenon ... -
Solidification–Stabilization of Heavy Metal–Contaminated Clays Using Gypsum: Multiscale Assessment
(American Society of Civil Engineers, 2018)Protecting the environment from hazardous pollutants associated with waste generation and disposal is a major concern that warrants further investigation. Chemical stabilization is commonly used to improve the engineering ... -
Numerical Approach to Creep of Rock Based on the Numerical Manifold Method
(American Society of Civil Engineers, 2018)The creep behaviors of stressed rock are of great practical significance because time-dependent deformation processes can lead to stable dissipation of energy, thereby reducing violent rockbursts or outbursts in underground ... -
Enhancement in Effectiveness of Cemented Stone Columns for Soft Clay Ground Improvement by Providing Underreamed Bulbs
(American Society of Civil Engineers, 2018)A straight-shafted cemented stone column technique for effective improvement of soft clay ground was reported in 217. The method involved transforming the conventionally used uncemented stone or granular mix fill material ... -
Failure Mechanism of Highly Stressed Rock Mass during Unloading Based on the Stress Arch Theory
(American Society of Civil Engineers, 2018)During excavation unloading, highly stressed rock masses at great depth exhibit failure modes with different scales, for instance, zonal disintegration, rockbursts, and super-low friction. The root cause of the failure ... -
Moving Loads on a Viscoelastic Foundation with Special Reference to Railway Transition Zones
(American Society of Civil Engineers, 2018)At railway transition zones between soft ground and stiffer structures, dynamic actions between the railcar, track, and subgrade induce differential settlements that may cause vibration and noise, compromise ride quality, ... -
Mechanical and Hydraulic Behaviors in a Single Fracture with Asperities Crushed during Shear
(American Society of Civil Engineers, 2018)Understanding the mechanical and hydraulic behaviors in a single fracture is important for underground rock engineering. In this study, coupled shear-flow tests were performed on five single fractures with regular dentate ... -
Shear-Induced Failure and Static Liquefaction in Reinforced Soil and Triaxial Tests
(American Society of Civil Engineers, 2018)In the Federal Highway Administration (FHWA) laboratory, a phenomenon was identified that reduces soil bearing capacity. This phenomenon arises in common situations, for example, reinforced soil, triaxial tests, mat ... -
Lateral-Moment Loading Capacity and Bearing Behavior of Suction Bucket Foundations for Offshore Wind Turbines in Sand
(American Society of Civil Engineers, 2018)Suction bucket foundations are promising foundation options for offshore wind turbines, which are usually subjected to a relative high lateral-moment loading. To investigate the lateral-moment loading capacity of bucket ... -
Transverse Dynamic Response of Circular Tunnels in Blocky Rock Mass Using Distinct-Element Method
