Numerical Modeling of the RAP Construction Process and Its Effects on RAP Behavior
(American Society of Civil Engineers, 2015)Although rammed aggregate piers (RAPs) have attracted much attention as a cost-beneficial ground improvement technique, their construction process and the other affecting parameters on the behavior of these geotechnical ... -
DEM Analyses of an Uplift Failure Mechanism with Pipe Buried in Cemented Granular Ground
(American Society of Civil Engineers, 2015)The uplift failure mechanism of buried pipe and its linked soil resistance are key concerns in pipe design. Although the uplift responses of pipe buried in remolded backfill have been discussed extensively, little effort ... -
Nonlinear Failure Surface and Pseudodynamic Passive Resistance of a Battered-Faced Retaining Wall Supporting c-Φ Backfill
(American Society of Civil Engineers, 2014)In the present analysis, a methodology is developed to calculate the pseudodynamic passive resistance on the back of a battered-faced retaining wall supporting cohesive-frictional backfill using the horizontal slice method ... -
Joint Strength and Wall Deformation Characteristics of a Single-Cell Geocell Subjected to Uniaxial Compression
(American Society of Civil Engineers, 2015)Geocells are three-dimensional expandable panels with a wide range of applications in geotechnical engineering. A geocell is made up of many internally connected single cells. The current study discusses the joint strength ... -
Dilatancy and Strength of an Unsaturated Soil-Cement Interface in Direct Shear Tests
(American Society of Civil Engineers, 2015)The dilatancy of a soil is significantly influenced by matric suction, and it affects the apparent friction angle and shear strength of the soil. To examine the influence of dilatancy on interface behavior, a series of ... -
Bearing Capacity of a Group of Stone Columns in Soft Soil
(American Society of Civil Engineers, 2015)Installation of stone column is a viable, cost effective, and environmentally friendly ground-improvement technique. Columns are made of compacted aggregate and are installed in weak soil as reinforcements to increase the ... -
Optimal Layout of Prefabricated Vertical Drains
(American Society of Civil Engineers, 2015)An approach to finding the optimal layout of prefabricated vertical drains (PVDs) in soft soil treatment, which has the minimum amount of PVDs and meets the requirements for the degree of consolidation, is proposed. Because ... -

Effect of Soil Density and Suction on the Elastic and Plastic Parameters of Unsaturated Silty Soil
(American Society of Civil Engineers, 2015)This paper presents the results of an experimental study on the effect of suction and compaction pressure on the elastic and plastic parameters of unsaturated silty soil. The experimental tests were performed in a specially ... -
Parametric Study of a Clayey Specimen Reinforced by a Granular Column
(American Society of Civil Engineers, 2015)This paper studies the effect of certain parameters closely related to the design of column foundations such as the improvement area ratio, especially at low values, e.g., 1 and 4%, and the grain size of the column material ... -
Interaction Mechanism between Two Large Rock Caverns
(American Society of Civil Engineers, 2015)Long-term stability of geotechnical structures is critical to any engineering design. Design of underground structures is initially planned using empirical approaches based on the rock mass–classification system. This ... -
Elastic–Brittle–Plastic Analysis of Circular Deep Underwater Cavities in a Mohr-Coulomb Rock Mass Considering Seepage Forces
(American Society of Civil Engineers, 2015)In a drained underwater cavity, seepage forces and pore-water pressure that develop around the cavity may affect the response of the rock mass. In this paper, a fully analytical solution is proposed for analysis of underwater ... -
