Plane Strain and Axially Symmetric Consolidation in Unsaturated Soils
(American Society of Civil Engineers, 2006)A method is presented for the analysis of coupled consolidation in unsaturated soils due to loading under conditions of plane strain as well as axial symmetry. The method is based on the transformation of the governing ... -
Parameter Optimization and Sensitivity Analysis for Disturbed State Constitutive Model
(American Society of Civil Engineers, 2006)Constitutive models for geologic materials and interfaces involve a number of parameters that need to be determined from appropriate laboratory tests. Because the test behavior is influenced by a number of factors such as ... -
Relationship between the Undrained Shear Strength, Water Content, and Mineralogical Properties of Fine-Grained Soils
(American Society of Civil Engineers, 2005)The relationship between the undrained shear strength of fine-grained soils and the water content can be described with a nonlinear function in which the type of soil is determined by two parameters. It is well known that ... -
Analytical Investigation of Friction Sleeve Length Effects on Stratigraphic Interpretation
(American Society of Civil Engineers, 2006)This paper presents an analytical investigation of the ability of friction sleeves of varying lengths to reliably identify layer interfaces and stratigraphic anomalies within the subsurface. Analytical and parametric ... -
Modeling Fully Coupled Oil–Gas Flow in a Dual-Porosity Medium
(American Society of Civil Engineers, 2005)A finite element model has been developed to simulate two-phase, (i.e., oil and gas) flow and solid deformation in a dual-porosity medium. The model accounts for coupling between solid deformations and fluid flow in both ... -
Experimental and Theoretical Investigations on Geocell-Supported Embankments
(American Society of Civil Engineers, 2006)This paper studies the advantages of geocell reinforcement on the performance of earth embankments constructed over weak foundation soil through laboratory model tests and proposes a simple method for the design of ... -
Thermomechanical Framework for the Constitutive Modeling of Asphalt Concrete
(American Society of Civil Engineers, 2006)This study is concerned with the constitutive modeling of asphalt concrete. Unlike most constitutive models for asphalt concrete that do not take into account the evolution of the microstructure of the material, this study ... -
Drilling Fluid Considerations in Design of Engineered Horizontal Directional Drilling Installations
(American Society of Civil Engineers, 2005)A literature review is presented that identifies a number of areas where procedures for the engineering design of bored installations in soil using horizontal directional drilling (HDD) can be improved through a more ... -
Collapse Loads for a Cylinder Embedded in Trench in Cohesive Soil
(American Society of Civil Engineers, 2005)This study investigates the relationship between the sediment resisting force and embedment depth for horizontal cylinders in a vertical trench. Plane-strain calculations of collapse loads are performed for a series of ... -
Displacements and Stresses Due to a Uniform Vertical Circular Load in an Inhomogeneous Cross-Anisotropic Half-Space
(American Society of Civil Engineers, 2006)In this work, we present the solutions for displacements and stresses along the centerline of a uniform vertical circular load in an inhomogeneous cross-anisotropic half-space with its Young’s and shear moduli varying ... -
Stiffness of a Flexible Circular Footing Embedded in an Elastic Half-Space
(American Society of Civil Engineers, 2006)This paper addresses the problem of a circular footing of finite but nonzero stiffness embedded in an isotropic nonhomogeneous elastic half-space. The problem is solved by coupling the scaled boundary finite-element method ... -
Dilatational and Compacting Behavior around a Cylindrical Cavern Leached Out in a Solid–Fluid Elastic Rock Salt
(American Society of Civil Engineers, 2005)A fluid-filled cylindrical cavern of circular cross section in a homogeneous infinite fluid-saturated polycristalline (salt) formation subjected to isotropic stress is set under internal pressure that differs from the ... -
Moment/Rotation Effects on Laterally Loaded Drilled Shaft Group Response
(American Society of Civil Engineers, 2005)Drilled shaft groups are often designed to resist lateral loads for transportation structures. The shaft group capacity usually corresponds to a load being applied at the shaft cap level. However, in abutment wall applications, ... -
Three-Dimensional Constitutive Model for Partially and Fully Saturated Soils
(American Society of Civil Engineers, 2005)Constitutive models for partially saturated soils often assume linear relationships for the variation of shear strength with suction and the shape of the partially saturated isotropic compression lines. It has been ... -
