Effect of Surcharge Pressure on Pile Static Axial Load Test Results
(American Society of Civil Engineers, 2014)This paper presents the effect of surcharge support pressure on pile load–settlement response during static load testing. A three-dimensional nonlinear finite-element model is developed to investigate the loading sequences ... -
Simplified Mapping Rule for Bounding Surface Simulation of Complex Loading Paths in Granular Materials
(American Society of Civil Engineers, 2014)This paper presents a bounding surface plasticity model that can be used to simulate complex monotonic and cyclic loading paths. A new mapping rule that only uses the last stress reversal point is introduced to describe ... -
Roscoe and Hvorslev Surfaces for Unsaturated Silty Soil
(American Society of Civil Engineers, 2014)The existence and characteristics of Roscoe and Hvorslev state boundary surfaces for unsaturated silty soil have been investigated by conducting controlled-suction triaxial tests on samples of an unsaturated compacted silty ... -
Modeling of the FWD Deflection Basin to Evaluate Airport Pavements
(American Society of Civil Engineers, 2014)The falling weight deflectometer (FWD) testing develops a deflection basin on the pavement surface. Depths of this deflection basin from the center of the falling weight are measured at different radial offsets. These ... -
Effects of Woody Vegetation on Seepage-Induced Deformation and Related Limit State Analysis of Levees
(American Society of Civil Engineers, 2014)Work in this paper investigates the effects of woody vegetation on soil hydraulic conductivity and the related probability of exceeding deformation-based performance limit states. A summary of results obtained from laboratory ... -
Constitutive Modeling and Testing of Interface between Backfill Soil and Fiber-Reinforced Polymer
(American Society of Civil Engineers, 2014)Geomaterials behave differently under different types of loadings, such as compression, shear, or tension; they exhibit weaker response in tension. To increase the tensile and shear strengths of the soil, different methods ... -
Modeling of Installation and Quantification of Shaft Resistance of Drilled-Displacement Piles in Sand
(American Society of Civil Engineers, 2014)Drilled-displacement (DD) piles are installed using a drilling tool consisting of a partial-flight auger and a displacement body. This tool is inserted and advanced in the ground by both a vertical force and a torque. ... -
Behavior of a Pressure-Grouted Soil-Cement Interface in Direct Shear Tests
(American Society of Civil Engineers, 2014)An interface between compacted soil and a structure is commonly encountered in various geotechnical engineering projects, e.g., soil nails, retaining walls, shallow foundations, pile foundations, and so on. The interface ... -
Modeling Cyclic Behavior of Rockfill Materials in a Framework of Generalized Plasticity
(American Society of Civil Engineers, 2014)Typical triaxial compression experiments were revisited to investigate the essential mechanical behavior of rockfill materials to be reflected in constitutive modeling, such as the nonlinear dependence of the strength and ... -
Volume Change Behavior of Fly Ash–Montmorillonite Clay Mixtures
(American Society of Civil Engineers, 2014)This paper presents the consolidation and swelling characteristics of fly ash–montmorillonite clay mixes. Nine types of fly ash samples collected from different thermal power plants of the Eastern part of India have been ... -
Application of an Artificial Neural Network for Modeling the Mechanical Behavior of Carbonate Soils
(American Society of Civil Engineers, 2014)Carbonate soils have some distinctive features such as compressibility and skeletal particle crushability that make them distinguishable from other types of soils. Many experimental models have been developed to describe ... -
Influence of Soil Reinforcement on Horizontal Displacement of MSE Wall
(American Society of Civil Engineers, 2014)Mechanically stabilized earth (MSE) walls offer simple construction techniques, pleasing aesthetics, and cost-effective solutions as an alternative to conventional gravity walls. However, design and construction should be ... -
Trench Stability under Bentonite Pressure in Purely Cohesive Clay
(American Society of Civil Engineers, 2014)Trench stability is a conventional geotechnical problem; however, current evaluations are often based entirely on empiricism. This paper uses numerical finite-element upper and lower bound limit analysis to produce stability ... -
