Analysis of Time-Dependent Bearing Capacity of a Driven Pile in Clayey Soils by Total Stress Method
(American Society of Civil Engineers, 2017)This paper proposes an analytical approach to evaluate the time-dependent bearing capacity of a driven pile in clayey soils by taking the pile installation and subsequent reconsolidation effects into consideration. The ... -
A Binary-Medium Constitutive Model for Artificially Structured Soils Based on the Disturbed State Concept and Homogenization Theory
(American Society of Civil Engineers, 2017)Triaxial compression tests were carried out on artificially structured soil samples at confining pressures of 25, 37.5, 50, 100, 200, and 400 kPa. A binary-medium constitutive model for artificially structured soils is ... -
Numerical Modeling of Rock Damage during Indentation Process with Reference to Hard Rock Drilling
(American Society of Civil Engineers, 2017)Drill bits, such as roller cones and hammers, are equipped with inserts; once in contact with the rock, each of them applies mainly a compressive action called indentation. In this paper, a numerical modeling-based analysis ... -
Formulation of Anisotropic Strength Criteria for Cohesionless Granular Materials
(American Society of Civil Engineers, 2017)Granular materials deposited under gravity usually exhibit inherent fabric anisotropy, which leads to profoundly varying strength under different loading directions in regard to the bedding plane that has been observed ... -
Approximate Simulation of Natural Structured Soft Clays Using a Simplified Bounding Surface Model
(American Society of Civil Engineers, 2017)A simple version of a recently proposed anisotropic elastoplastic bounding surface model was used to simulate the mechanical behavior of natural Shanghai soft clay. The characteristics of stress–strain curves attributable ... -
Influence Factors Involving Rainfall-Induced Shallow Slope Failure: Numerical Study
(American Society of Civil Engineers, 2017)Assessment of rainfall-induced shallow slope failures is important for reducing damage to infrastructures as well as for the safety of people living close to hazardous areas. The rainfall intensity-duration thresholds for ... -
Development of a Constitutive Model to Predict the Behavior of Cement-Treated Clay during Cementation Degradation: C3 Model
(American Society of Civil Engineers, 2017)Many researchers have indicated how cementation allows treated soft clays to sustain a higher yield mean effective stress at the same void ratio as its reconstituted state, and thus, the strength of clay treated with cement ... -
Numerical Analysis of the Effects of Cracks on the Moisture-Diffusion Coefficient of Unsaturated Soils

Three-Dimensional Stability of Two-Stage Slope in Inhomogeneous Soils
(American Society of Civil Engineers, 2017)The three-dimensional (3D) stability calculations of soil slopes are often focused on homogeneous soils in the published literature. However, strength inhomogeneity is a common phenomenon in slope engineering. The purpose ... -
Influence of Size and Load-Bearing Mechanism of Piles on Seismic Performance of Buildings Considering Soil–Pile–Structure Interaction
(American Society of Civil Engineers, 2017)Pile foundations are usually used to transmit foundation loads through soil strata of low bearing capacity to deeper soil or rock strata with a higher bearing capacity and stiffness. The type and size of a pile foundation ... -

Dynamic Behavior Analysis of High-Speed Railway Ballast under Moving Vehicle Loads Using Discrete Element Method
(American Society of Civil Engineers, 2017)Considering the real irregular shapes of ballast particles and complete track skeleton, a two-dimensional discrete element model is built to investigate the dynamic behavior of high-speed railway (HSR) ballasted track. ... -
Love-Wave Propagation in an Inhomogeneous Orthotropic Medium Obeying the Exponential and Generalized Power Law Models
(American Society of Civil Engineers, 2017)Based on the theory of elasticity, the analytical solutions of the Love-wave dispersion equation are generated for the inhomogeneous orthotropic medium, for which the Young’s modulus (Ex, Ey, Ez), shear modulus (Gxy, Gyz, ... -
Novel Underhand Cut-and-Fill Stoping Method and Mechanical Analysis of Overlying Backfill
(American Society of Civil Engineers, 2017)Underhand cut-and-fill stoping is an efficient, sustainable mining method that is particularly applicable to complicated mining conditions in which both the peripheral rocks and the orebody are extremely unstable. Considering ... -
