(American Society of Civil Engineers, 2023/06/01)Low-amplitude repetitive drained loading may hinder the long-term performance of engineered and natural systems. This study examines the volumetric and shear response of a uniform quarzitic sand subjected to repetitive ... -
Thermal Effects on Shear Characteristics of Unbound Granular Materials under Drained Conditions
(American Society of Civil Engineers, 2023/04/01)In this study, the thermally induced changes in the shear characteristics of unbound granular materials (UGMs) were investigated. A series of drained shear tests were conducted using a large-scale triaxial apparatus under ... -
3D Numerical Assessment of Rammed Aggregate Pier Performance under Dynamic Loading in Liquefiable Soils
(American Society of Civil Engineers, 2023/03/01)Ground improvement (GI) techniques have shown promise in effective liquefaction mitigation, but the physical mechanisms governing their three-dimensional (3D) response during dynamic loading are not yet fully understood. ... -
On the In Situ Cyclic Resistance of Natural Sand and Silt Deposits
(American Society of Civil Engineers, 2023/04/01)This study presents cyclic resistances of an instrumented medium dense sand (i.e., the Sand Array) and medium plastic silt (i.e., the Silt Array) deposit deduced from in situ dynamic testing using the controlled ... -
Shallow Seafloor Sediments: Density and Shear Wave Velocity
(American Society of Civil Engineers, 2023/05/01)Near-surface seafloor properties affect offshore mining and infrastructure engineering. Shallow seafloor sediments experience extremely low effective stress, and consequently, these sediments exhibit very low in-situ ... -
Multimode Free-Vibration Decay Column: Small-Strain Stiffness and Attenuation
(American Society of Civil Engineers, 2023/06/01)This study presents a simplified resonant column testing method to obtain small-strain dynamic properties of soils in both torsional and flexural vibrations. The method exploits free vibration decay responses of the system ... -
Experimental Study on the Time-Dependent Oedometric Compression Behavior of Calcareous Sand
(American Society of Civil Engineers, 2023/05/01)A series of compression tests were carried out on two types of calcareous sand to study the time-dependent behavior of calcareous sand under oedometric conditions. Consolidation, creep, stress relaxation, and constant ... -
Water Retention Curve–Based Design Method for the Artificial Ground Freezing: The Isarco River Underpass Tunnels within the Brenner Base Tunnel Project
(American Society of Civil Engineers, 2023/03/01)The paper presents an interpretation of the temperature monitored during the application of artificial ground freezing in the Isarco River Underpass tunnel, within the Brenner Base Tunnel project. The observations gathered ... -
Mechanical Characterization of Coarse-Grained Waste Rocks Using Large-Scale Triaxial Tests and Neuroevolution of Augmenting Topologies
(American Society of Civil Engineers, 2023/06/01)Mining operations produce large quantities of waste rocks, which are usually disposed of in waste rock piles, but can also be valorized in mine haul roads. The engineering performance of these haul roads significantly ... -
Static and Cyclic Liquefaction of Copper Mine Tailings
(American Society of Civil Engineers, 2023/05/01)Motivated by recent failures of tailings storage facilities (TSFs) around the globe, the tailings community is actively working to better understand the mechanical behavior of mine tailings. This study presents a geotechnical ... -
Pullout Capacity of Single and Biwing Anchors in a Soft Clay Deposit: Model Investigation in a Centrifuge and FEM Predictions
(American Society of Civil Engineers, 2023/07/01)One of the ways to install plate anchors in deep seabed is to drop the anchor system from the sea level and allow it to initially embed in the seabed under its own weight. Further dragging would cause the anchor to rotate ... -
