RISSeismic Performance of an Embankment Underlain by a Liquefiable Layer and Supported by Spatially Variable Soil-Cement Wall
Publisher: ASCE
Abstract: This paper presents the results of nonlinear deformation analyses of an embankment on a spatially variable, liquefiable foundation soil reinforced with spatially variable soil-cement (SC) wall. The objective is to evaluate ...
Liquefaction Potential and Sediment Ejecta Manifestation of Thinly Interbedded Sands and Fine-Grained Soils: Palinurus Road Site in Christchurch Subjected to 2010–2011 Canterbury Earthquake Sequence
Publisher: ASCE
Abstract: The effect of spatial variability on the liquefaction prediction and liquefaction-induced ground failure of a soil profile with thinly interbedded layer of sand and clay was examined using simplified procedures and fully ...
Stochastic Slope Stability Analysis of an Embankment Supported by Isolated Soil–Cement Columns Considering Spatial Variability
Publisher: ASCE
Abstract: Two-dimensional, nonlinear, finite-difference analyses were used to investigate the stability of an embankment supported by spatially variable soil–cement columns. This study evaluated the improvement/merit of employing ...
Effects of Fines Content and Relative Density on Erosion and Recession of Predominantly Sandy Beach–Bluff System
Publisher: ASCE
Abstract: Exploratory experiments including a series of flume and geotechnical tests were conducted to assess the effects of fines content and relative density on the erosion and recession of predominantly sandy beach and bluff. The ...
Effect of Fines Content on Calcium Carbonate Precipitation and Thermal Properties of Biocemented Sand
Publisher: American Society of Civil Engineers
Abstract: In this study, the impacts to soil thermal properties during and after biocementation via microbially induced calcite precipitation (MICP) method on silty silica sand specimens with varying fines content (0%, 5%, and 15%) ...
Variation of Small-Strain Shear Modulus of Unsaturated Silt under Successive Cycles of Drying and Wetting
Publisher: ASCE
Abstract: A new framework is developed to extend an existing small-strain shear modulus (Gmax) model to determine Gmax of unsaturated silty soils along different paths of the soil water retention curve (SWRC) including the scanning ...
Dynamic Centrifuge Tests to Evaluate the Seismic Performance of an Embankment Resting on Liquefiable Ground Improved by Unreinforced and Reinforced Soil–Cement Columns
Publisher: ASCE
Abstract: A series of centrifuge experiments were conducted to identify different internal failure modes of a group of soil-cement (SC) columns (e.g., shearing and tension due to bending) under combined effects of embankment ...
Application of Geothermal Bridge Deck Deicing Systems to Mitigate Concrete Deterioration from Temperature Fluctuation: Model Scale Experiments
Publisher: American Society of Civil Engineers
Abstract: This paper presents experimental testing evaluating the ability of a bridge deck deicing system to mitigate concrete deterioration from thermal stresses, frost action, and early-age cracking. Two experimental bridge deck ...
Dynamic Centrifuge Tests of Soft Clay Reinforced by Soil–Cement Grids
Publisher: American Society of Civil Engineers
Abstract: A pair of large centrifuge tests was conducted to evaluate the effect of soil-cement grid reinforcement on the seismic response of a deep soft soil profile. The soil profile consisted of a 23-m-thick layer of lightly ...
Centrifuge Tests of Cone-Penetration Test of Layered Soil
Publisher: ASCE
Abstract: Two centrifuge model tests were used to examine the effect of soil interlayering on the measured cone-penetration resistance in a layered soil model. The first centrifuge model included four soil profiles: two uniform loose ...
