Bounding Surface Cam-Clay Model with Cohesion for Cement-Admixed Clay
(American Society of Civil Engineers, 2017)This paper proposes a constitutive model for cement-admixed soil based on the concept that the effect of cementitious bonding can be accounted for by incorporating a cohesion term into the Cam-clay flow rule. The cohesion ... -
New Rock Bolt Model and Numerical Implementation in Numerical Manifold Method
(American Society of Civil Engineers, 2017)A beam-element-based rock bolt model is proposed in this paper. The proposed model can not only simulate the compression and tension deformations of bolts in the rock block but also capture the interaction between the bolt ... -
Behavior of Rigid-Faced Reinforced Soil-Retaining Walls Subjected to Different Earthquake Ground Motions
(American Society of Civil Engineers, 2017)A study of the seismic behavior of rigid-faced reinforced soil-retaining walls subjected to scaled earthquake ground motions is presented in this paper. A numerical model was developed and validated to simulate the ... -
Numerical Simulations of Wave–Structure–Soil Interaction of Offshore Monopiles
(American Society of Civil Engineers, 2017)Ocean energy converters (OECs) are becoming a more popular source of electricity generated from the ocean. The main obstacle associated with the use of OECs is their high initial installation cost. In light of this, ... -
Effect of Suction Stress on Critical State of Compacted Silty Soils under Low Confining Pressure
(American Society of Civil Engineers, 2016)The critical-state behavior of an unsaturated dilative specimen under low confining pressure from 0 to 50 kPa was examined by conducting a constant water content–compression (CWCC) test on unsaturated compacted silty soil. ... -
Interface Behavior from Suction-Controlled Direct Shear Test on Completely Decomposed Granitic Soil and Steel Surfaces
(American Society of Civil Engineers, 2016)A soil-structure interface is defined as the contact surface between a soil and a structure through which stresses are transferred from the soil to the structure or vice versa. The ultimate shear strength at the interface ... -
