Multiscale Approach for Mechanical Characterization of Organic-Rich Shale and Its Application
(American Society of Civil Engineers, 2019)Mechanical behavior of organic-rich shale strongly influences the stimulation performance of hydraulic fracturing. This article presents an approach for the characterization and evaluation of mechanical properties of shale ... -
Viscoelastic Analysis of Geogrid-Reinforced Asphaltic Pavement under Different Tire Configurations
(American Society of Civil Engineers, 2018)The new generation of wide-base tires and the traditional dual-tire assembly are the main types of tire configurations used in the drive and trailing axles of trucks. However, the response of pavement to these configurations ... -
Verification of the Kaiser Effect in Rocks under Tensile Stress: Experiment Using the Brazilian Test
(American Society of Civil Engineers, 2018)For many aspects of rock engineering, it is important to measure the in situ stresses, not only under compression but also under tension. Brazilian tests were performed to generate tensile stress in granite samples. The ... -
Three-Dimensional Static and Seismic Stability Analysis of a Tunnel Face Driven in Weak Rock Masses
(American Society of Civil Engineers, 2018)Face stability is an important issue for tunnel designs and constructions. This study investigated the seismic face stability of tunnels drilling in heavily fractured rock masses that follow the generalized Hoek–Brown yield ... -
Evolution of Soil Arching: 2D Analytical Models
(American Society of Civil Engineers, 2018)Three soil-arching evolution patterns in unreinforced piled embankments were observed in a series of two-dimensional (2D) model tests using a multitrapdoor test setup. These include the triangular expanding pattern, the ... -
Centrifuge Modeling of a Saturated Clay Ground under Cyclic Loading
(American Society of Civil Engineers, 2018)To study the effects of traffic loading, three centrifuge tests were carried out on the response of a saturated clay ground under sinusoidally cyclic vertical loading. The clay ground was overconsolidated at its top to ... -
Soil–Building Interaction Analysis with Nearby Water Body, Based on an Input Wavefield
(American Society of Civil Engineers, 2018)In this article, a three-dimensional (3D) linear finite-element method with an included water volume for examining the soil–building interaction based on a three-component input seismic wavefield is presented. A seismic ... -
Methodology for Estimating Creep Deformation from Consolidation Deformation in 1D Compression
(American Society of Civil Engineers, 2018)In geotechnical engineering, characterization of time-dependent behavior of clayey soils under one-dimensional (1D) constant stress has been controversial. In some special cases, the creep deformation is insignificant ... -
Transversely Isotropic Creep Model for Rocks
(American Society of Civil Engineers, 2018)The transverse isotropic (TI) creep behavior of rocks was investigated using laboratory tests and constitutive modelling. Triaxial stepwise and multiple-stage creep tests were performed to investigate the TI creep behavior ... -
Surface Loading over a Transversely Isotropic and Multilayered System with Imperfect Interfaces: Revisit Enhanced by the Dual-Boundary Strategy
(American Society of Civil Engineers, 2018)Layered structures in nature or created by humans are very common, and various numerical methods have been proposed to analyze them. In this paper, uniform surface loading over a transversely isotropic layered system with ... -
Propagation Attenuation of Plane Waves in Single-Phased Soil by Periodic Pile Barriers
(American Society of Civil Engineers, 2018)Pile barriers have been broadly used to decrease the effect of ground vibration generated by machines or traffic. In recent years, the periodic theory of solid-state physics was introduced to study the reduction characteristics ... -
Analytical Prediction for Tunneling-Induced Ground Movements with Modified Deformation Pattern
(American Society of Civil Engineers, 2018)In current methods for predicting ground movement caused by tunneling, the center of the tunnel is usually thought of as the focus of ground-movement vectors for convenience. In reality, the ground-movement vectors around ... -
Comparative Study of 2D and 3D Micromechanical Discrete Element Modeling of Indirect Tensile Tests for Asphalt Mixtures
(American Society of Civil Engineers, 2018)Based on imaging and the discrete element method (DEM), this study mainly aims to compare the two-dimensional (2D) and three-dimensional (3D) micromechanical modeling of the indirect tensile (IDT) tests for asphalt mixtures. ... -
Factor of Safety of Three-Dimensional Stepped Slopes
(American Society of Civil Engineers, 2018)Stepped slopes have been widely used in slope and excavation engineering to improve slope stability. On the basis of the three-dimensional (3D) horn failure mechanism, this article proposes a new method to estimate the ... -
Analytical Solution for Dissolution-Timescale Reactive Transport in Fluid-Saturated Porous Rocks
(American Society of Civil Engineers, 2018)Reactive transport, in which chemical dissolution reactions dissolve dissolvable materials in fluid-saturated porous rocks, is very common in groundwater pollution and geoenvironmental engineering. Because of coupled ... -
Analytical Solution to One-Dimensional Consolidation in Unsaturated Soil Deposit Incorporating Time-Dependent Diurnal Temperature Variation
(American Society of Civil Engineers, 2018)Several experimental studies have demonstrated that temperature changes may significantly influence the deformation of unsaturated soils. Thus, there is an essential need to develop a predictive framework for unsaturated ... -
Influence of Anisotropy and Nonhomogeneity on Stability Analysis of Slurry-Support Trenches
