RISHysteretic Model for the Evolution of Water Retention Curve with Void Ratio
Publisher: American Society of Civil Engineers
Pitfalls in Interpretation of Gravimetric Water Content–Based Soil-Water Characteristic Curve for Deformable Porous Media
Publisher: American Society of Civil Engineers
Abstract: Pitfalls in the common approaches to obtaining material parameters from soil-water characteristic curves (SWCCs) are discussed, and the typical mistakes made in the literature are highlighted. Particular attention is given ...
Assessing the Stress–Deformation and Safety Factor against Sliding in Reinforced Deep Urban Excavations in Unsaturated Soils
Publisher: American Society of Civil Engineers
Abstract: There has been limited research conducted to date on the role and significance of soil parameters in an unsaturated state on the amount of deformation and safety of reinforced deep urban excavations. This study investigates ...
Effect of Gradation and Particle Shape on Small-Strain Young’s Modulus and Poisson’s Ratio of Sands
Publisher: American Society of Civil Engineers
Abstract: The influence of gradation and particle shape on the small-strain Young’s modulus of dry sands is investigated through a comprehensive set of resonant column tests in the flexural mode of vibration. Experiments are performed ...
Exploring the Effects of Initial Fabric Anisotropy due to Preshearing Stress History in Different Directions on the Undrained Behavior of Loose Sands
Publisher: American Society of Civil Engineers
Abstract: The main objective of this study was to investigate the response of uniform sand under constant volume (i.e., undrained) conditions and how it is influenced by the initial anisotropy induced in the soil fabric due to ...
Modified Duncan-Chang Constitutive Model for Modeling Supported Excavations in Granular Soils
Publisher: ASCE
Abstract: Numerical analyses have been widely used to investigate the stability of deep excavations. The results of this type of analyses rely on the constitutive model that is adopted for the analyses. Although many advanced ...
