Can Soil Arching Be Insensitive to ϕ ?
(American Society of Civil Engineers, 2010)Arching is a common phenomenon that is encountered in backfilling behind retaining walls, trenches, or underground voids in the mine. Marston’s equation has been widely used and modified for computing stresses within ... -
Anisotropy in the Spatial Distribution of Roller-Measured Soil Stiffness
(American Society of Civil Engineers, 2010)The geostatistical analysis of roller-measured soil properties (from continuous compaction control and intelligent compaction) is required for advanced quality control/quality assurance of earthwork and asphalt compaction. ... -
Large Deformation Finite-Element Analysis of Submarine Landslide Interaction with Embedded Pipelines
(American Society of Civil Engineers, 2010)Submarine landslides represent one of the most significant geohazards on the continental slope in respect of the risk they pose to infrastructure such as deep water pipelines. A numerical approach, based on the finite-element ... -
Seismic Responses of Reinforced Soil Retaining Walls and the Strain Softening of Backfill Soils
(American Society of Civil Engineers, 2012)Considering that most geosynthetic-reinforced soil structures (GRS) are backfilled with well-compacted granular soils exhibiting evident strain-softening, it is expected that the mobilized soil strength beyond the peak ... -
