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 ...
Notes on the Prediction of Extreme Ship Response
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this note the relation between two simple approaches to estimate the extreme ship response used when no, or a limited, amount of data are available is discussed. The first one employs the long term distribution of the ...
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, ...
Analytical Solution for Electroosmotic Consolidation Considering Nonlinear Variation of Soil Parameters
Publisher: American Society of Civil Engineers
Abstract: Electroosmotic consolidation can be used as an efficient technique for soft soil improvement. Considering the limitation in previous theories that soil parameters keep constant during electroosmotic consolidation, the ...
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 ...
Rotary Contact Method for 5-Axis Tool Positioning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new 5-axis tool positioning algorithm called the rotary contact method (RCM) for open concave surface machining using the toroidal cutter is developed. The RCM comes from the ...
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 ...
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 ...
State-Dependent Constitutive Model for Rockfill Materials
Publisher: American Society of Civil Engineers
Abstract: A series of large-scale triaxial compression tests on Tacheng rockfill material (TRM) showed that the dilatancy and stress-strain behaviors were significantly influenced by density and pressure. The critical state friction ...
