Identification Method of Deformation Localization in DEM-Simulated Granular Geomaterials Based on Contact Deformations
(American Society of Civil Engineers, 2017)Deformation localization of granular geomaterials is critical in analyzing the stability of earth structures. This paper presents a new and simple method for quantitatively identifying deformation localization in the ... -
Seismic Translational Failure Analysis of MSW Landfills Using Modified Pseudo-Dynamic Approach
(American Society of Civil Engineers, 2017)For landfills situated in regions of high seismicity, seismic inertial forces may be a triggering factor for the translational stability of municipal solid waste (MSW) landfills. This paper applies a modified pseudodynamic ... -
Numerical Study of Consolidation Effect on the Response of Passive Piles Adjacent to Surcharge Load
(American Society of Civil Engineers, 2017)Piles subject to soil lateral movement are often referred to as passive piles. The response of passive piles in clayey soils adjacent to surcharge is not only dependent on the soil intrinsic behavior but also on the loading ... -
Mechanical Properties of Brown Coal under Different Loading Conditions
(American Society of Civil Engineers, 2017)The Latrobe Valley in Victoria, Australia has the largest brown coal deposit in the world, where large-scale brown coal mines were established in the early 1970s. The geotechnical stability of mining batters requires a ... -
Analysis of Interfering Circular Footings on Reinforced Soil by Physical and Numerical Approaches Considering Strain-Dependent Stiffness
(American Society of Civil Engineers, 2017)This paper numerically examines the bearing capacity, settlement, and failure kinematics of two closely spaced circular footings on reinforced soil. A number of large-scale tests are performed to identify the influence of ... -
Analytical Models for Estimation of Slope Stability in Homogeneous Intact and Jointed Rock Masses with a Single Joint
(American Society of Civil Engineers, 2017)In the present paper two analytical models are proposed for the estimation of slope stability in homogeneous intact and jointed rock masses with strain-softening behavior and a single joint, as nonlinear functions of basic ... -
Factors Affecting Piping Erosion Resistance: Revisited with a Numerical Modeling Approach
(American Society of Civil Engineers, 2017)Piping poses a great threat to dam and levee systems across the globe. Although various straightforward approaches have been used to assess piping resistance, a fundamental understanding of the complex soil–flow interactions ... -
Laboratory Investigation on Strength Characteristics of Expansive Soil Treated with Jute Fiber Reinforcement
(American Society of Civil Engineers, 2017)Based on an extensive list of research work, expansive soil is renowned for its swelling-shrinkage property. Despite the wealth of research, the strength characteristics of expansive soil, which are more complicated than ... -
Differential Settlements of Embankment Treated by Cement Fly-Ash Gravel Pile and Sheet Pile in Freeway Extension Constructions
(American Society of Civil Engineers, 2017)The differential settlement between the newly built embankment and the old one is becoming a serious problem in the extension construction of roadways in some areas. To solve this problem, cement fly-ash gravel (CFG) piles ... -
Method of Generation and Model of Calculation of Arbitrary Curved Slip Surfaces for Three-Dimensional Convex and Concave Slopes
(American Society of Civil Engineers, 2017)Compared with the three-dimensional (3D) simple slope, actual slopes often have irregular slope topography. The 3D convex and concave slopes are two important types of actual slopes. To analyze the stability of 3D convex ... -
Quasi-Static Rheology of Granular Media Using the Static DEM
(American Society of Civil Engineers, 2017)In contrast to the conventional discrete element method (DEM), no dynamic or damping variables are needed in the static DEM. This study aims at investigating the potential of the static DEM in modeling the quasi-static ... -
