Simulation of Split Hopkinson Pressure Bar Tests on Sands Using the Discrete-Element Method
(ASCE, 2022-2-1)Split Hopkinson pressure bar (SHPB) tests have been used extensively to study the stress–strain behavior of sand under high strain-rate conditions. However, the low impedance of sand leads to specimens not attaining stress ... -
Evaluation of Low Stress and Cracking Zones in the Core of a High Rockfill Dam in a Relatively Narrow Canyon Using 3D Numerical Modeling
(ASCE, 2022-3-1)This paper documents the development of low stress and fracture zones in the core of the 177-m-high Masjed-E-Soleyman rockfill dam––which has a clay core and was built in a relatively narrow canyon––using three-dimensional ... -
Changes in the Permeability and Permeability Anisotropy of Reconstituted Clays under One-Dimensional Compression and the Corresponding Micromechanisms
(ASCE, 2022-2-1)It is important to assess the permeability characteristics of clays in the prediction of the postconstruction settlement of geotechnical projects on clay grounds. The coefficient of permeability in the vertical direction ... -
Experimental Study on Uniaxial Compression Behavior of Fissured Loess Before and After Vibration
(ASCE, 2022-2-1)Fissured loess is one of the sources of geological hazards such as landslides and collapse under dynamic load. In this study, acrylic pipes with an inner diameter of 62 mm were processed into molds with different inclination ... -
Soil Arching in Dry Sand: Numerical Simulations Using Double-Slip Plasticity Gradient Model
(ASCE, 2022-2-1)The arching phenomenon is intrinsic to granular materials and is a manifestation of the effects of their discrete microstructure. The fundamental mechanism of arching is the ability of discrete granular particles to transfer ... -
Thickness Calculation of Accumulative Damaged Zone by Rock Mass Blasting Based on Hoek–Brown Failure Criterion
(ASCE, 2022-2-1)Tunnel excavation by cyclic blasting caused accumulative damages to the surrounding rocks, reducing the intactness of the rock mass. The blasting impact contributes to the formation of an excavation damaged zone (EDZ) ... -
Bearing Capacity Factors for Rough Conical Footing by Viscoplasticity Finite-Element Analysis
(ASCE, 2022-1-1)Many researchers have computed the bearing capacity of the strip and circular footings resting on the soil with the low and medium friction angle (ϕ ≤ 35°) by employing the finite-element method (FEM). It is reported that ... -
Dynamic Properties of Spatially-Varied Pond Ash within a Coal Ash Pond
(ASCE, 2022-3-1)Abandoned ash pond beds have been considered for their reclamation through the construction of lightweight structures. Under static conditions, an ash pond bed can sustain these structures but its stability must be ascertained ... -
Development of Coupled FEM and Fuzzy Rules–Based Procedures for Mitigation of Uncertainty in Forecasting Stability of Underground Pillars
(ASCE, 2022-2-1)Stability of underground working depends on geomechanical properties of rocks as well as geometrical and operational parameters of excavation. In this study, a fuzzy rule-based method, minimizing the subjectivity in rock ... -
Data-Based Modeling Approaches for Short-Term Prediction of Embankment Settlement Using Magnetic Extensometer Time-Series Data
(ASCE, 2022-2-1)Developing data-driven predictive models is highly desirable for monitoring the condition of infrastructure assets but is dependent on the generation of large data sets that are regularly updated. This represents a challenge ... -
Compressive Wave Isolation of Lightweight Equipment Very Close to a Vibration Source Using a Rubber Sheet
(ASCE, 2022-1-1)Protecting sensitive and/or valuable facilities is of concern when placing them near a machine foundation. There are methods available and well-studied such as wave barriers to reduce transmitted vibration and noises in ... -
Stochastic Foundation to Solving Transient Unsaturated Flow Problems Using a Fractional Dispersion Term
(ASCE, 2022-1-1)Mathematical modeling of unsaturated water seepage through soils uses the core concepts of continuum mechanics. More precisely, it combines the continuum mass balance equation and Darcy–Buckingham Law into the Richards ... -
In Situ State of Tailing Silts Using a Numerical Model of Piezocone Penetration Test Developed by Norsand Model
(ASCE, 2022-1-1)Tailings are the reservoirs containing a high proportion of saturated silts that may be extremely difficult to sample in their undisturbed condition. This is mostly due to the fabric disturbance and densification that can ... -
