Abstract: The effects of fines content on the liquefaction behavior and the dynamic response of gravelly soils were evaluated in this study. A total of six models of level-ground profiles of two saturated gravel-sand-fines mixtures ...

Abstract: Previous studies investigating dynamic responses of gravelly soil were limited to high-strain conditions, in which a high level of pore-water pressure is developed, leading to a significant reduction in shear strength and ...

Abstract: A series of centrifuge tests were performed to evaluate the backward erosion piping behavior that occurred in models with the same soil and same dimensions and to investigate the influence of the seepage length, exit-hole ...

Abstract: Determination of strain in resonant column and torsional shear (RC/TS) tests is complicated due to nonuniform stress–strain variation occurring linearly with the radius in a soil specimen in torsion. The equivalent radius ...

Abstract: This study presents the results from a series of centrifuge modeling tests conducted to investigate the backward erosion piping across a sandy foundation underlying an impervious cohesive layer with a defined exit hole. ...

Abstract: A series of centrifuge tests were conducted to examine self-weight consolidation, dynamic response, liquefaction potential, and slope stability of mine tailings alone and in mixtures with waste rock. Mixture ratio of waste ...

Abstract: Hurricane Katrina was one of the worst natural disasters in U.S. history. The effects of the hurricane were particularly devastating in the city of New Orleans. Most of the damage was due to the failure of the levee system ...

Abstract: Centrifuge modeling of the 17th Street Canal and Orleans Canal North levees was performed in this study. During hurricane Katrina the levees on the 17th Street Canal failed, leading to breaches in the outfall canal in the ...
