RISElastoplastic 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 ...
New Method for Improvement of Rockfill Material with Polyurethane Foam Adhesive

Upper-Bound Solution for Flat Cavity Expansion Model
Publisher: American Society of Civil Engineers
Abstract: In this paper, an upper-bound solution for the FCEM is proposed to study the effect of the plastic behavior of soil on the interpretation of a flat dilatometer test. Kinematically admissible displacement fields for the ...
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 ...
Differentiation of Noisy Experimental Data for Interpretation of Nonlinear Stress-Strain Behavior
Publisher: American Society of Civil Engineers
Abstract: Interpretation of nonlinear stress-strain behavior of a material may require differentiating the load-displacement curve constructed from experimental data. Pressuremeter and torsional shear tests in geotechnical engineering ...

Publisher: American Society of Civil Engineers
Abstract: In this paper, an upper-bound solution for the FCEM is proposed to study the effect of the plastic behavior of soil on the interpretation of a flat dilatometer test. Kinematically admissible displacement fields for the ...
Construction of Water Pond Using Bioslurry-Induced Biocementation
Publisher: ASCE
Abstract: This paper presents a methodology to construct a water pond in sand using bioslurry layer via the microbially induced carbonate precipitation (MICP) process. Bioslurry is calcium carbonate crystals containing high-urease ...
Large Deformation Numerical Analysis of Displacement-Controlled Cylindrical Cavity Expansion under Anisotropic Initial Stress
Publisher: ASCE
Abstract: This paper proposes an empirical solution to calculate the average ultimate cavity wall pressure (UCWP) of cavity expansion in undrained clay under anisotropic stress through large deformation finite element analysis using ...
Interactions of an Energy Pile with Several Traditional Piles in a Row
Publisher: ASCE
Abstract: A full-scale test was carried out to investigate the interactions between an energy pile and four traditional piles connected to the same overlying reinforced beam. A series of sensors was installed in the energy pile, ...
Theoretical Solution for Cavity Expansion in Crushable Soil
Publisher: ASCE
Abstract: This paper proposed a theoretical solution for cavity expansion in crushable soils. The constitutive relations of the crushable soils were described by the breakage mechanics model that explains the grain crushing induced ...
