Constitutive Modeling of Kinematic Hardening Behavior of Saturated Anisotropic Soils
(American Society of Civil Engineers, 2017)A new three-dimensional cone-cap limit-state surface (LSS) model is proposed for cross-anisotropic, saturated, cohesionless, or cohesive remolded soils in consideration of anisotropic yielding and kinematic hardening. ... -
Numerical and Experimental Investigations of Granular Anchor Piles in Loose Sandy Soil Subjected to Uplift Loading
(American Society of Civil Engineers, 2017)The granular anchor pile (GAP) system is one of the relatively new innovative ground-improvement techniques used to sustain the tensile loads. This paper presents the behavior of a GAP system in a loose sandy soil. The ... -
Numerical Evaluation of Passive Earth-Pressure Coefficients under the Effect of Surcharge Loading
(American Society of Civil Engineers, 2017)A numerical protocol was developed for the evaluation of the passive earth-pressure coefficients (Kpq) for the case of an inclined rigid wall retaining an inclined cohesionless backfill loaded with a uniform surcharge. The ... -
Gradation and Packing Characteristics Affecting Stability of Granular Materials: Aggregate Imaging-Based Discrete Element Modeling Approach
(American Society of Civil Engineers, 2017)Unbound aggregate base and subbase in layered pavement structures provide an essential function of wheel load distribution through proper angular or crushed particle interlocking of coarse aggregate particles in the granular ... -

Stability Analyses of Waste Rock Barricades Designed to Retain Paste Backfill
(American Society of Civil Engineers, 2017)Cemented paste backfill (CPB) is widely applied in underground mines around the world. Prior to stope backfilling, barricades need to be built in drifts near drawpoints to retain the flowable fill. A number of reported ... -
Development of New Three-Dimensional Coal Mass Strength Criterion
(American Society of Civil Engineers, 2017)In this study, laboratory tests were conducted to obtain the geomechanical properties for the coal matrix and coal discontinuities. Computed tomography (CT) scanning technology was then used to detect the pre-existing ... -
Effects of Anisotropy, Initial Stress, Heterogeneity, and Gravity on Torsional Wave Propagation
(American Society of Civil Engineers, 2017)The present paper provides the results of a study of the propagation of torsional surface waves in an initially stressed self-reinforced layer lying over a dry sandy Gibson half-space in the presence of initial stress and ... -
Model Uncertainty of Eurocode 7 Approach for Bearing Capacity of Circular Footings on Dense Sand
(American Society of Civil Engineers, 2017)This paper presents a critical evaluation of the model factor M = qu,m/qu,c for Eurocode 7 calculating the bearing capacity of circular footings on dense sand, where qu,m = measured capacity and qu,c = Eurocode 7 calculated ... -
