Effect of Anisotropy and Destructuration on Behavior of Haarajoki Test Embankment
(American Society of Civil Engineers, 2009)This paper investigates the influence of anisotropy and destructuration on the behavior of Haarajoki test embankment, which was built by the Finnish National Road Administration as a noise barrier in 1997 on a soft clay ... -
Closure to “Analysis of Deep Moisture Barriers in Expansive Soils. I: Constitutive Model Formulation” by Eduardo Rojas, Miguel P. Romo, and Refugio Cervantes
(American Society of Civil Engineers, 2009) -
Limit Analysis of Rigid Foundations on Floating Columns
(American Society of Civil Engineers, 2009)This study applies the limit analysis to estimate the bearing capacity of a rigid foundation on a soil reinforced by a group of floating columns. The lower bounds of the bearing capacity are derived in terms of a dimensionless ... -
Effect of Strain Rate and Strain Softening on the Penetration Resistance of Spudcan Foundations on Clay
(American Society of Civil Engineers, 2009)In practice, natural soils exhibit strain-rate dependency and also soften as they are sheared and remolded. Traditional design approaches, however, have been developed based on idealized rate-independent perfectly plastic ... -
Time-Dependent Mechanical Behavior of a Granular Medium Used in Laboratory Investigations
(American Society of Civil Engineers, 2009)The time-dependent mechanical response of an artificial granular medium consisting of glass beads is experimentally examined by performing one-dimensional creep tests on both saturated and dry specimens. The time-dependent ... -
One-Dimensional Viscous Behavior of Clay and Its Constitutive Modeling
(American Society of Civil Engineers, 2009)One-dimensional viscous behavior of clay was evaluated by performing drained one-dimensional compression tests, and drained triaxial compression tests. In both types of tests, the strain rate was changed stepwise many times ... -
Predicting the Uniaxial Compressive Strength and Static Young’s Modulus of Intact Sedimentary Rocks Using the Ultrasonic Test
(American Society of Civil Engineers, 2009)The uniaxial compressive strength and static Young’s modulus -
Two-Dimensional Discrete Element Theory for Rough Particles
(American Society of Civil Engineers, 2009)The surfaces of real sands are often rough and a discrete element modeling of rough granulates is very important to understand the behavior of real sands. This paper presents a two-dimensional discrete element method (DEM) ... -
Numerical Investigation of the Stress State in Inclined Backfilled Stopes
(American Society of Civil Engineers, 2009)Evaluating the stresses in backfilled stopes constitutes a critical step for insuring underground mine safety and for analyzing backfill response. In recent years, the writers have presented several methods for conducting ... -
Three-Dimensional Joint/Interface Element for Rough Undulating Major Discontinuities in Rock Masses
(American Society of Civil Engineers, 2008)Major civil engineering structures are being constructed now a days in complex geological environment with faults, shear zones, and other major discontinuities. These major discontinuities can cause a variety of problems ... -
Evaluation of Smear Zone Extent Surrounding Mandrel Driven Vertical Drains Using the Cavity Expansion Theory
(American Society of Civil Engineers, 2008)In this study, an attempt is made to analyze the extent of the smear zone caused by mandrel driven vertical drains, employing the cavity expansion theory for soft clay obeying the modified Cam-clay model. The predictions ... -
Torsional Waves in Self-Reinforced Medium
(American Society of Civil Engineers, 2009)The present paper discusses the frequency equation for torsional waves in a self-reinforced medium. It can be seen that the phase velocity of torsional waves in a self-reinforced rod of circular cross section is influenced ... -

Finite-Element Modeling of Cementitiously Stabilized Beams Using a Smeared Fracture Approach
(American Society of Civil Engineers, 2009)Cracking is considered a vital distress in a pavement structure. It generally initiates and propagates (bottom up and/or surface down) causing damage to the overall pavement structure. Most previous numerical modeling ... -
Numerical Modeling of Seismic Response of Rigid Foundation on Soft Soil
(American Society of Civil Engineers, 2008)A numerical model was developed to simulate the response of two instrumented, centrifuge model tests on soft clay and to investigate the factors that affect the seismic ground response. The centrifuge tests simulated the ... -
Effect of Arching on Uplift Capacity of Pile Groups in Sand
(American Society of Civil Engineers, 2008)In this paper an analytical method has been proposed to predict the net ultimate uplift capacity of pile groups embedded in sand considering the arching effect. This method takes into consideration the embedded length -
Observations on Return Mapping Algorithms for Piecewise Linear Yield Criteria
(American Society of Civil Engineers, 2008)This paper shows that for perfect plasticity, the closest point projection method (CPPM) and the cutting plane algorithm (CPA) for return mapping are exactly equivalent for piecewise linear yield criteria under both ... -
Model for Consolidation-Induced Solute Transport with Nonlinear and Nonequilibrium Sorption
(American Society of Civil Engineers, 2008)A numerical model, called CST2, is presented for coupled large strain consolidation and solute transport in saturated porous media. The consolidation and solute transport algorithms include the capabilities of a previous ... -
Immediate Settlement of Shallow Foundations Bearing on Clay
(American Society of Civil Engineers, 2008)Immediate and long-term settlement checks are an integral part of foundation design. Therefore, reasonably accurate estimates of the immediate settlement of shallow foundations bearing on clay are necessary, particularly ... -
Analytical and Numerical Modeling of Consolidation by Vertical Drain beneath a Circular Embankment
(American Society of Civil Engineers, 2008)In the analysis of axisymmetric problems, it is often imperative that aspects of geometry, material properties, and loading characteristics are either maintained as constants or represented by continuous functions in the ...
