Analysis of a Single Pile under Vertical and Torsional Combined Loads in Two-Layered Nonhomogeneous Soil
(American Society of Civil Engineers, 2019)Pile foundations are inevitably subjected to combined vertical-torsional (V-T) loadings in offshore engineering contexts. This article proposes an analytical method for calculating the V-T response of a single pile in ... -
Hysteresis Model for Dynamic Load under Large Strains
(American Society of Civil Engineers, 2019)An appropriate constitutive model under cyclic shear loading must be able to characterize the behavior both at small and large strains correctly and consider the effects of degradation phenomena and the load history at the ... -
Behavior and Critical Failure Modes of Strip Foundations on Slopes under Seismic and Structural Loading
(American Society of Civil Engineers, 2019)This paper presents a numerical study on capacity envelopes of strip foundations placed on the top and the face of two typical soil slopes at different offset distances and subjected to earthquake effects using the ... -
Deformation Analysis of Geosynthetic-Encased Stone Column–Supported Embankment considering Radial Bulging
(American Society of Civil Engineers, 2019)This study presents an analytical solution for predicting the vertical settlement behavior of geosynthetic-encased stone columns (GESCs) and GESC-supported embankments, taking into account the radial bulging deformation ... -
Modeling Geogrid Pullout Behavior in Sand Using Discrete-Element Method and Effect of Tensile Stiffness
(American Society of Civil Engineers, 2019)In this study, a series of numerical pullout tests was performed using the discrete-element method (DEM) to investigate the micromechanical behavior of geogrid pullout and the effect of geogrid tensile stiffness. Geogrid–soil ... -
Analytical Solution for Consolidation of Band-Shaped Drain Based on an Equivalent Annular Drain
(American Society of Civil Engineers, 2019)In general, prefabricated vertical drains (PVDs) used in practice are usually manufactured in band shapes. To analyze its consolidation in cylindrical coordinate system, the band-shaped drain was usually converted into an ... -
Deformation and Load-Bearing Characteristics of Step-Tapered Piles in Clay under Lateral Load
(American Society of Civil Engineers, 2019)The step-tapered pile foundation is a relatively new structure. For this reason, current literature on step-tapered piles is still not systematic or comprehensive. Thus, it is of the utmost importance to carry out tests ... -
Novel 3D Failure Criterion for Rock Materials
(American Society of Civil Engineers, 2019)The failure criterion of rock material has been used in geotechnical engineering to assess the failure behavior of rocks under complicated stress conditions. In the present study, a new failure criterion is proposed; it ... -
Modeling Cyclic Embedment of Deep-Water Pipelines Using Large Displacement Limit Analysis
(American Society of Civil Engineers, 2019)The as-laid embedment is a key design element of deep-water pipelines, as it significantly affects the longitudinal and transverse pipe–soil interaction and thermal insulation. Due to the small-amplitude oscillations driven ... -
Performance of Cement Asphalt Mortar in Ballastless Slab Track over High-Speed Railway under Extreme Climate Conditions
(American Society of Civil Engineers, 2019)The cement asphalt (CA) mortar layer acts as the key component of the China Railway Track System II (CRTS-II) type ballastless slab track to ensure stability, durability, and cost maintenance. However, it was found to be ... -
Deformation Analysis of a Geosynthetic-Encased Stone Column and Surrounding Soil Using Cavity-Expansion Model
(American Society of Civil Engineers, 2019)This article presents an analytical solution to predict the deformation of a geosynthetic-encased stone column (GESC) and the surrounding soil using a cylindrical cavity-expansion model. The cavity-expansion model is used ... -
Simulation of Liquefaction and Retrogressive Slope Failure in Loose Coarse-Grained Material
(American Society of Civil Engineers, 2019)Flowslides and retrogressive slope failures are usually triggered from a significant drop of shear strength in loose coarse-grained materials, including static liquefaction and successive large deformations. A 4-step ... -
Analytical Solution for Stress Distribution around Arbitrary Stopes Using Evolutionary Complex Variable Methods
(American Society of Civil Engineers, 2019)In this study, we proposed an evolutionary complex variable method (ECVM) to find the analytical solution for the stress distribution in an infinite homogeneous, isotropic, and elastic rock mass. This ECVM was a combination ... -
Experimental Investigation of the Coupled Influence of Rate of Loading and Contact Time on the Frictional Behavior of Quartz Grain Interfaces under Varying Normal Load
(American Society of Civil Engineers, 2019)In this study, the coupled influence of contact time and rate of loading on the interface behavior of quartz grains was examined experimentally. The rate of loading is considered not just a tangential (or sliding) rate but ... -
Discontinuous Deformation Analysis with Potential Contact Forces
(American Society of Civil Engineers, 2019)In conventional discontinuous deformation analysis (DDA), the procedure called open–close iteration is adopted to enforce the contact condition, which needs to repeatedly fix and remove the artificial springs between blocks ... -
Thermo-Hydro-Mechanical Model for Unsaturated Clay Soils Based on Granular Solid Hydrodynamics Theory
