Influence of Particle Breakage on Critical State Line of Rockfill Material
Publisher: American Society of Civil Engineers
Abstract: The influences of particle breakage on the position of the critical state line (CSL) were systematically investigated in this paper through a series of large-scale triaxial compression tests on Tacheng rockfill material ...
Constitutive Modeling for Transparent Granular Soils
Publisher: American Society of Civil Engineers
Abstract: Transparent granular soil was recently found to be greatly useful for observations of the internal deformation in geotechnical model tests. Therefore, it is necessary to investigate the stress–strain and stress–dilatancy ...
Model Tests on Soil Movement during the Installation of Piles in Transparent Granular Soil
Publisher: American Society of Civil Engineers
Abstract: This paper presents model tests on the displacement characteristics of flat-ended piles, pipe piles, and piles with a cone tip of 45º in a transparent granular soil. The testing setup consisted of transparent granular soil, ...
Elastoplastic Constitutive Model for Rockfill Materials Considering Particle Breakage
Publisher: American Society of Civil Engineers
Abstract: Particle breakage has a great influence on stress-strain behaviors of rockfill materials. A new relative breakage was proposed for rockfill materials. A critical state line incorporating particle breakage was termed as a ...
Strength and Dilatancy Behaviors of Dense Modeled Rockfill Material in General Stress Space
Publisher: American Society of Civil Engineers
Abstract: The strength and dilatancy behaviors of modeled dense rockfill material were systematically investigated through a series of true triaxial compression tests at different minor principal stress and intermediate principal ...
Formulation of Cross-Anisotropic Failure Criterion for Granular Material
Publisher: American Society of Civil Engineers
Abstract: The failure anisotropy of geomaterial is inherently related to the microstructure such as grain arrangement, bedding, and crack pattern. This paper presents a formulation of an anisotropic failure criterion in three-dimensional ...
Effects of Load Duration and Stress Level on Deformation and Particle Breakage of Carbonate Sands
Publisher: ASCE
Abstract: Time-dependent deformation of crushable soils attributable to particle breakage could dominate the postconstruction stability of high rockfill dams and pile foundations. The evolutionary trends of the volumetric strain, ...
New Simple Breakage Index for Crushable Granular Soils
Publisher: ASCE
Abstract: Degradation of geomaterials, that is, particle breakage, can be harmful to the full life-cycle stability of practical engineering; for example, rockfill dam, energy-pile foundation, railway embankment, and retaining wall. ...
Constitutive Modeling for Overconsolidated Clays Based on Disturbed State Concept. II: Validation
Publisher: American Society of Civil Engineers
Abstract: The disturbed state concept (DSC)-based model for overconsolidated clay was proposed mainly in a previous paper that aims to analyze the influences of the model parameters on model predictions, calibrations of the model ...
Constitutive Modeling for Overconsolidated Clays Based on Disturbed State Concept. I: Theory
Publisher: American Society of Civil Engineers
Abstract: The disturbed state concept (DSC) is widely used to capture the cracking, breaking, heating, softening, and hardening behaviors of geomaterials. In this study, a constitutive model for overconsolidated clays is proposed ...
