Generalized Analytical Solution for the Consolidation of Unsaturated Soil under Partially Permeable Boundary Conditions
(American Society of Civil Engineers, 2017)Previous studies have usually idealized the boundary conditions of unsaturated soil as absolutely permeable or impermeable. However, this assumption is not sound for the majority of cases where the boundary is partially ... -
Effect of TBM Advance in the Structural Response of Segmental Tunnel Lining
(American Society of Civil Engineers, 2017) -
Love Wave Behavior in Composite Fiber-Reinforced Structure

Evolution of Water Table and Pore-Water Pressure in Stopes with Submerged Hydraulic Fill
(American Society of Civil Engineers, 2017)Hydraulic fill is often used to fill large underground voids created during mining operations. It is produced and distributed as a slurry at a pulp density (P) of 65–75% (solids content). Consequently, a substantial amount ... -
Modeling the Behavior of Expansive Soils Using Effective Stresses
(American Society of Civil Engineers, 2017)In the past 15 years, different researches have shown that the effective-stress approach represents a simple and precise way to generate fully coupled constitutive models for unsaturated soils. This is so because the ... -
Upper-Bound Limit Analysis of Shield Tunnel Stability in Undrained Clays Using Complex Variable Solutions for Different Ground-Loss Scenarios

Mechanism of Cracking in Dams Using a Hybrid FE-Meshfree Method
(American Society of Civil Engineers, 2017)Cracking has a significant impact on dam safety. A discontinuous hybrid finite-element meshfree (FE-meshfree) method, which inherits advantages from both the FEM and the meshfree method, was developed to investigate the ... -
New Ways to Represent Interparticle Forces as Effective Stresses in a Macroscopic Continuum
(American Society of Civil Engineers, 2017)This paper presents a simple proof of an initially counterintuitive result that the interparticle effective forces in a particulate aggregate can be meaningfully represented using an infinite number of uniaxial stress ... -
Estimation of Shaft Radial Displacement beyond the Excavation Bottom before Installation of Permanent Lining in Nondilatant Weak Rocks with a Novel Formulation
(American Society of Civil Engineers, 2017)The convergence-confinement method (CCM) applies to circular tunnels in in situ stress fields in which all three principal stresses are equal and the rock mass exhibits elastic-perfectly plastic shear failure. As radial ... -
Effects of Microfracture on Wave Propagation through Rock Mass
(American Society of Civil Engineers, 2017)This paper presents an investigation of wave propagation through microfractured rock mass. The effects of microfracture on wave propagation were observed by a series of scanning electron microscope (SEM) tests and wave-velocity ... -
Three-Dimensional Discrete-Element Method Analysis of Stresses and Deformations of a Single Geogrid-Encased Stone Column
(American Society of Civil Engineers, 2017)The discrete-element method (DEM) has been successfully used to simulate the behavior of granular material and was used in this study to analyze the stresses and deformations of a single geogrid-encased stone column under ... -
Influence of Particle Size and Gradation on the Stress-Dilatancy Behavior of Granular Materials during Drained Triaxial Compression
(American Society of Civil Engineers, 2017)This paper examines the potential influence of particle-size distribution on stress-dilatancy behavior of granular materials from the results of 35 conventional drained triaxial compression tests. Seven different grain-size ... -
Physical Derivation of Effective Stress from Balance Law and Experimental Evidence
(American Society of Civil Engineers, 2017)It has long been discussed whether Terzaghi’s expression for effective stress holds true for all saturated soils. To examine the physical basis of the effective stress expression, a new mechanical model is proposed. According ... -
Analytical Solution for the Consolidation Behavior of Deep Cement Mixed Column–Improved Ground
(American Society of Civil Engineers, 2017)This paper presents an analytical solution for the consolidation behavior of deep cement mixed (DCM) column–improved ground on the basis of the equal strain condition. The proposed analytical solution accounted for the ... -
Adaptation of Method of Fragments to Axisymmetric Cofferdam Seepage Problem
