Coupled Time Domain Integration Algorithm for Numerical Manifold Method
(American Society of Civil Engineers, 2017)A temporal coupled explicit–implicit time integration algorithm is proposed to improve the computational efficiency of the numerical manifold method (NMM) for seismic stability analysis of rock slope. It includes a coupled ... -
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 ... -
Behavior of Rigid-Faced Reinforced Soil-Retaining Walls Subjected to Different Earthquake Ground Motions

Drained Instability in Loose Granular Material
(American Society of Civil Engineers, 2016)The constant shear drained (CSD) test is considered an appropriate test to simulate the instability behavior of soils in slopes under water infiltration conditions or lateral stress relief. However, contradiction of the ... -
Numerical Procedures for Simulating Earthquake Fault Rupture Propagation
(American Society of Civil Engineers, 2017)Numerical simulations of earthquake fault rupture propagation can be used to design structures to resist damage from induced ground deformations. Several researchers have developed numerical models for analyzing the responses ... -
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 ... -
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, ... -
Fully Softened Shear Strength for Soil Slope Stability Analyses
(American Society of Civil Engineers, 2017)The fully softened shear strengths of soils, mudstones, and shales of different plasticities and gradations were measured at low (10 and 25 kPa), intermediate (50 and 100 kPa), and high (200, 300, and 400 kPa) effective ... -
Particle Flow Modeling of Rock Blocks with Nonpersistent Open Joints under Uniaxial Compression
