Displacement Hazard Analysis of Earth Structures Affected by Subduction Zone and Shallow Crustal Earthquakes
Publisher: ASCE
Abstract: Common practice for evaluating the seismic performance of earth dams uses design ground motions selected to be consistent with a target design response spectrum, which are subsequently used in dynamic analyses that estimate ...
Static and Cyclic Liquefaction of Copper Mine Tailings
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Mechanical Response of Mine Tailings under Constant Shear Drained Loading
Publisher: American Society of Civil Engineers
Abstract: Several tailings dam failures have highlighted the potential for instability under prevailing drained conditions, which can be represented in the laboratory using constant shear drained (CSD) loading. In this study, the ...
Epistemic Uncertainty Treatment in Seismically Induced Slope Displacements Using Polynomial Chaos
Publisher: ASCE
Abstract: Performance-based probabilistic approaches (PBPAs) for estimating seismically-induced slope displacements (D) provide hazard-consistent estimates through the evaluation of D hazard curves (DHCs), and hence, its use in ...
Seismic Slope Displacement Procedure for Interface and Intraslab Subduction Zone Earthquakes
Publisher: ASCE
Abstract: The seismic performance assessment of earth slopes and systems requires an estimate of the seismically-induced slope displacement (D). Modified Newmark-type analyses are useful to develop an estimate of D. Most simplified ...
Impact of Ergodic and Nonergodic Ground Motion Estimation on the Earthquake Resilience of Shared Distributed Energy Resource Systems
Publisher: ASCE
Abstract: Distributed energy resource systems (DERs), such as rooftop solar panels, are gaining traction in the energy sector to improve infrastructure resilience to earthquakes by facilitating electricity sharing in seismic regions ...
Cadia TSF Failure Assessment Considering Triggering and Posttriggering Mechanisms
Publisher: ASCE
Abstract: Numerous recent failures of tailings storage facilities (TSFs) (e.g., the 2019 Brumadinho failure in Brazil, the 2018 Cadia failure in Australia) have occurred in the last decade, providing important case histories ...
CPTu-Based Spatial Variability Assessment of Thickened and Conventional Mine Tailings
Publisher: American Society of Civil Engineers
Abstract: The Global Industry Standard on Tailings Management (GISTM) promotes performance-based approaches in geotechnical assessments. Hence, characterizing the spatial variability of deposited tailings is expected to be a key ...
