New Approach to Determine Seismic Passive Resistance on Retaining Walls Considering Seismic Waves
(American Society of Civil Engineers, 2013)Calculation of seismic earth pressure is important for design of retaining walls in earthquake-prone areas. Existing analytical methods for computation of seismic passive earth pressure do not consider the effect of Rayleigh ... -
Influence of Anisotropic Small Strain Stiffness on the Deformation Behavior of Geotechnical Structures
(American Society of Civil Engineers, 2013)Constitutive models based on the multilaminate framework naturally account for strain-induced anisotropy, but inherent anisotropy needs additional considerations. A recently introduced feature is the capability of the model ... -
New Load Transfer Hyperbolic Model for Pile-Soil Interface and Negative Skin Friction on Single Piles Embedded in Soft Soils
(American Society of Civil Engineers, 2014)A proper load transfer model describing the pile and surrounding soil interaction is important for accurately predicting the behavior of piles. In this paper, a new load transfer hyperbolic model for the pile-soil interface ... -
Experimental and Numerical Study of Micropiles to Reinforce High Railway Embankments
(American Society of Civil Engineers, 2013)The construction of railway embankments on loose beds using reinforcing elements results in a modification of the embankments slope, which significantly reduces the amount of earthworks. In addition, reinforcement of both ... -
Influence of Destructuration of Soft Clay on Time-Dependent Settlements: Comparison of Some Elastic Viscoplastic Models
(American Society of Civil Engineers, 2015)The time-dependent settlement of soft soils following the application of surface loading may be modeled using elastic viscoplastic constitutive models to describe the soil behavior. For applied loadings that increase the ... -
True Triaxial Tests on Cross-Anisotropic Deposits of Fine Nevada Sand
(American Society of Civil Engineers, 2013)An experimental program was designed to study the effects of cross-anisotropy under three-dimensional conditions on fine Nevada sand using tall prismatic specimens. Eighteen drained tests were performed using a true triaxial ... -
Dynamic Soil-Structure Interaction of a Gravity Quay Wall and the Effect of Densification in Liquefiable Sites
(American Society of Civil Engineers, 2014)The lateral spreading of backfill soil caused by displacement of gravity-type quay walls is a major concern for geotechnical engineers. This paper evaluates the efficiency of a technique for mitigation of damage to quay ... -
Interpretation of Cone Factor in Undrained Soils via Full-Penetration Finite-Element Analysis
(American Society of Civil Engineers, 2013)The cone penetration test is widely used to interpret the undrained shear strength of soil. The interpretation methods are commonly based on bearing capacity, cavity expansion, or strain-path methods. In this paper, the ... -
Discrete Element and Experimental Investigations of the Earth Pressure Distribution on Cylindrical Shafts
(American Society of Civil Engineers, 2014)Experimental and numerical studies have been conducted to investigate the earth pressure distribution on cylindrical shafts in soft ground. A small-scale laboratory setup that involves a mechanically adjustable lining ... -
Bearing Capacity of Strip Foundations in Reinforced Soils
(American Society of Civil Engineers, 2014)A method is proposed to determine the ultimate bearing capacity of a strip footing placed over granular and cohesive-frictional soils that are reinforced with horizontal layers of reinforcements. The reinforcement sheet ... -
Coupling Rock-Fracture Propagation with Thermal Stress and Fluid Flow
(American Society of Civil Engineers, 2013)This paper describes the theory behind a recent extension of a two-dimensional (2D) boundary-element code, -
Stress Dilatancy of Natural Soft Clay under an Undrained Creep Condition
(American Society of Civil Engineers, 2015)The stress–dilatancy relationship is a key point to capture the evolution of both strains and excess pore pressure during an undrained creep of natural soft clay. This paper focuses on investigating the stress dilatancy ... -
