Abstract: This paper presents the results of numerical simulations of the resilient modulus test used to mechanically characterize the resilient behavior of aggregate materials, commonly used in pavement bases and subbases. The ...

Abstract: A coupled hydromechanical model was used to analyze the mesoscale pore fluid flow and microscale solid phase deformation of saturated granular soils. The fluid motion was idealized using averaged Navier–Stokes equations, ...

Abstract: The surface and downhole accelerations, and pore‐water pressures recorded during the 1987 earthquakes at a site in the Imperial Wildlife Management Area (Imperial County, Calif.) are used to obtain direct estimates of the ...

Abstract: The seismic records of the Long Valley Earth Dam are utilized in order to shed some light on the salient features of the dam nonlinear behavior. The dam is well instrumented with 22 accelerographs tied with a common ...

Abstract: Widespread liquefaction occurred in Kobe, Japan, during the 1995 Hyogoken-Nanbu earthquake. At the reclaimed Port Island in Kobe, the observed large-scale liquefaction was documented by acceleration records from a downhole ...

Abstract: Centrifuge modeling of pore pressure buildup in a sand deposit as a result of shaking is evaluated by comparison with a large-scale experiment. In large-scale Test SG-1, a 5.6-m-thick, mildly sloping deposit of hydraulic ...

Abstract: The characteristics of soil response during earthquake excitations, at a site in Lotung, Taiwan are identified using the Lotung large scale seismic test (LSST) data. A technique is developed to evaluate soil shear ...

Abstract: The Lotung large-scale seismic test (LSST) site in Taiwan was instrumented in 1985 with an array of downhole and surface accelerometers, by the Electric Power Research Institute (EPRI), Palo Alto, Calif., and the Taiwan ...

Abstract: This paper reports the results of model-based simulations of 1-g shake table tests of level and sloping saturated granular soils subject to seismic excitations. The simulations utilize a transient fully coupled continuum-fluid ...

Abstract: This paper examines in detail the mechanics of lateral spreading observed in a full-scale test of a sloping saturated fine sand deposit, representative of liquefiable, young alluvial and hydraulic fill sands in the field. ...
