Effects of Separation on the Behavior of Soil-Pile Interaction in Liquefiable Soils
(American Society of Civil Engineers, 2012)Separation and sliding between soil and pile have a significant effect on the complex behavior of pile groups under dynamic condition. In addition to separation between soil and pile, the behavior of soil medium surrounding ... -
Thermally Induced Behavior of the Openings in Rock Mass Affected by High Temperatures
(American Society of Civil Engineers, 2011)The temporary storage of hot water in openings excavated in rock may be worthwhile for multiple land-use applications, environmental safeguards, and energy conservation. When used for hot water storage, the rock mass around ... -
Arching in Soils Applied to Inclined Mine Stopes
(American Society of Civil Engineers, 2011)Determination of stress distribution, giving due consideration to arching mechanism within minefill stopes, is of great importance because of its influence on the ground stability, ore recovery, and cost effectiveness. ... -
Numerical Analysis of One-Dimensional Consolidation in Layered Clay Using Interface Boundary Relations in Terms of Infinitesimal Strain
(American Society of Civil Engineers, 2011)The interface boundary relations are derived in this study for the numerical analysis of one-dimensional consolidation in multilayered clay profiles. The finite difference solutions are formulated based on Mikasa’s ... -
Discussion of “Neural Network Modeling of Resilient Modulus Using Routine Subgrade Soil Properties” by Musharraf Zaman, Pranshoo Solanki, Ali Ebrahimi, and Luther White

Uplift Capacity of Axially Loaded Piles in Clays
(American Society of Civil Engineers, 2011)The present study aims at determining the uplift capacity of axially loaded piles in clays whose undrained cohesion increases linearly with depth. With the application of the axisymmetric static limit analysis approach, ... -
Finite Difference Method for Computation of 1D Pollutant Migration through Saturated Homogeneous Soil Media
(American Society of Civil Engineers, 2011)The physical processes such as advection, dispersion, and diffusion and interaction between the solution and the soil solids such as sorption, biodegradation, and retention processes have been considered in the governing ... -
Parameter Optimization of Rock Failure Criterion Using Error-in-Variables Approach
(American Society of Civil Engineers, 2011)Parameters of rock failure criteria are estimated using an optimization procedure based on appropriate objective function. In the development of objective function, it is assumed that the independent variables are free ... -
Practical Subgrade Model for Improved Soil-Structure Interaction Analysis: Model Development
(American Society of Civil Engineers, 2011)This note outlines the theoretical development of a new subgrade model with inherent spring coupling called the modified Kerr-Reissner (MK-R) model. The MK-R model is a novel hybrid that synergistically combines the ... -
Micromechanical Aspects of Liquefaction-Induced Lateral Spreading
(American Society of Civil Engineers, 2010)This paper reports the results of model-based simulations of 1-g shake table tests of level and sloping saturated granular soils subject to seismic excitations. The simulations utilize a transient fully coupled continuum-fluid ... -
Simple Yield Surface Expressions Appropriate for Soil Plasticity
(American Society of Civil Engineers, 2010)The objective of this paper is to present a number of simple, practical, and useful analytical expressions of a yield surface for geomaterials. In classical plasticity, the analytical expression of a yield surface defines ... -
On a Possible Role of Rayleigh Surface Waves in Dynamic Slope Failures
(American Society of Civil Engineers, 2010)This contribution addresses the effect of a surface wave on the dynamic behavior of a slope. In particular, the interaction of a Rayleigh surface wave, possibly generated by an earthquake or nearby blasting, with a simple ... -
Measuring and Modeling Proportion-Dependent Stress-Strain Behavior of EPS-Sand Mixture<sup>1</sup>
(American Society of Civil Engineers, 2010)A geofoam was produced by blending expanded polystyrene (EPS) beads and sands in proportions. The formed mixtures, known as EPS-sands, were 26–63% lighter than general earth fills (e.g., sand). Consolidated-drained (CD) ... -
Consolidation Behavior of Soils Subjected to Asymmetric Initial Excess Pore Pressure Distributions
(American Society of Civil Engineers, 2010)Although the consolidation settlements beneath foundations and embankments are rarely one dimensional, Terzaghi’s one-dimensional consolidation theory is often applied to these situations to approximate consolidation ... -
