RISInfluence of Spatial Variability on the Uniaxial Compressive Responses of Rock Pillar Based on 3D Random Field
Publisher: ASCE
Abstract: Knowledge of the uniaxial compressive responses of rock mass is crucial for evaluating the stability of rock pillar in underground engineering. The inherent spatial variabilities of rock mass properties are generally ignored ...
Investigating the Compatibility Mechanism of Bitumen Modified with Photo-Oxidative Aging of Polyethylene Using Molecular Dynamics Simulation
Publisher: ASCE
Abstract: Oxidation degrees of recycled polyethylene (RPE) particles affect the compatibility between RPE and bitumen, resulting in the low properties of RPE-modified bitumen and uncontrolled production technology. In this study, ...
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, ...
Probabilistic Assessment of Serviceability Limit State of Diaphragm Walls for Braced Excavation in Clays
Publisher: American Society of Civil Engineers
Abstract: Braced excavation systems are commonly required to ensure stability in the construction of basements for shopping malls and underground transportation facilities. For excavations in deposits of soft clays, stiff retaining ...
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 ...
Development of a Modeling Method and Parametric Study of Seepage-Induced Erosion in Clayey Gravel
Publisher: ASCE
Abstract: The aim of this study is to develop a method to simulate the behaviors of clayey gravel during water erosion by using computational fluid dynamics–discrete element method. The fluid phase was solved using the “fixed ...
Effect of Low-Density Polyethylene and Crumb Rubber Blends with Different Ultraviolet Aging Degrees on the Storage Stability of Bitumen Based on Molecular Dynamics Simulation
Publisher: American Society of Civil Engineers
Abstract: Although crumb rubber (CR) modified bitumen has been widely used in bitumen pavement, the issue of storage stability has not been resolved. Waste low-density polyethylene (LDPE), a new modifier, has been introduced to ...
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 ...
