Analysis of Dispersion and Damping Characteristics of Love Wave Propagation in Orthotropic Visco-Elastic FGM Layer with Corrugated Boundaries
(ASCE, 2020)A mathematical model was designed to analyze the propagation characteristics of Love waves traversing through an orthotropic visco-elastic FGM layer under initial stress lying over a half-space with void pores. The uppermost ... -
Long-Term Deformation of Highway Subgrade under Coupling Effect of Traffic Load and Drying–Wetting Cycles
(ASCE, 2020)Subgrade long-term deformation was investigated by taking the effects of both traffic load and drying–wetting cycles into consideration on the basis of numerical calculation and laboratory experiments. The total subgrade ... -
Earth Pressure Buildup in Impacting Earth Flow behind a Barrier
(ASCE, 2020)Barriers are commonly used to intercept landslide flows or debris flows. The presence of a barrier changes the flow condition and leads to a buildup of earth pressure in a zone behind the barrier. Investigating this buildup ... -
Behavior of Tire-Geogrid–Reinforced Retaining Wall System under Dynamic Vehicle Load
(ASCE, 2020)The surge in the number of cars has generated enormous numbers of waste tires in recent years. How to utilize the waste tires in engineering construction in an environmentally friendly way is a problem that China and many ... -
Interpretation of Dynamic Pile Load Testing for Open-Ended Tubular Piles Using Finite-Element Method
(ASCE, 2020)For a foundation to perform safely, the ultimate strength of each pile must satisfy the structural and geotechnical requirements. Pile load testing is considered to be a direct method for determining the ultimate geotechnical ... -
Reduced Model of One-Dimensional Unsaturated Flow in Heterogeneous Soils with Spatially Stochastic Soil Hydraulic Conductivities
(ASCE, 2020)A reduced model for unsaturated flow in one-dimensional layered soils with local stochastic soil hydraulic conductivity is proposed. The reduced model relies on an improved closure assumption compared with straightforward ... -
Development and Verification of a New Simplified Method for Calculating Settlement of a Thick Soil Layer with Nonlinear Compressibility and Creep
(ASCE, 2020)Variable compressibility must be considered in settlement calculation of soft soil stratums, especially for thick soil layers. This study proposes a new simplified method to calculate the settlement of a thick soil layer ... -
Experimental Study of Bolt-Anchoring Mechanism for Bedded Rock Mass
(ASCE, 2020)This study examined the effectiveness of different bolt anchoring systems in bedded rock to determine the bolt anchoring mechanism. The rock failure under shear and tensile stresses was evaluated. The results showed that ... -
Crushing and Flooding Effects on One-Dimensional Time-Dependent Behaviors of a Granular Soil
(ASCE, 2020)Particle crushing contributes significantly to the time-dependent compression behaviors of crushable granular soils. It also is widely accepted that flooding aggravates the breakage level of soil particles. This study ... -
Effects of Wall Movements on Performance of Integral Abutment Bridges
(ASCE, 2020)Abutment walls in integral abutment bridges (IABs) move in a cyclic pattern in response to temperature-induced expansion and/or contraction of the bridge superstructure. The repetitive abutment movements cause an active-wedge ... -
Simulating Undrained Tests on Unsaturated Soils
(ASCE, 2020)A simple fully coupled constitutive model for unsaturated soils is presented and used to simulate the behavior of unsaturated soils subjected to undrained conditions. The mechanical model is based on the modified critical ... -
Three-Dimensional State-Dependent Fractional Plasticity Model for Soils
(ASCE, 2020)To capture the nonassociated state-dependent constitutive behavior of soils subjected to different initial densities and pressures, a novel approach, the fractional-order (α) plasticity, was developed, which extends the ... -
Predicting Shear Strength of Unsaturated Soils over Wide Suction Range
(ASCE, 2020)Unsaturated soils over a wide suction range are widespread in nature. The shear strength of unsaturated soils is a fundamental property in various geotechnical designs. In this paper, a systematic study was conducted to ... -
Probabilistic Analysis of Soil-Water Characteristic Curve of Bentonite: Multivariate Copula Approach
(ASCE, 2020)Measurement of the soil-water characteristic curve (SWCC) is time-consuming for soils such as bentonites. It is desirable to develop a first-hand estimate of SWCC from a statistical generalization of the available data. A ... -
