Modeling Permanent Deformation of Unbound Granular Materials under Repeated Loads
(American Society of Civil Engineers, 2010)Finite-element analysis on a pavement structure under traffic loads has been a viable option for researchers and designers in highway pavement design and analysis. Most of the constitutive drivers used were nonlinear elastic ... -
Monitoring and Modeling Grout Efficiency of Lifting Structure in Soft Clay
(American Society of Civil Engineers, 2010)An inclined eight-story reinforced concrete building on a thick soft clay deposit was leveled by compensation grouting with short gel time grout injected through sleeved pipes. The monitoring system is used to record the ... -
Algorithm to Generate a Discrete Element Specimen with Predefined Properties
(American Society of Civil Engineers, 2010)The discrete element method is a powerful numerical tool in simulating the behavior of granular materials. It bridges the gap between continuum mechanics and physical modeling investigations. In spite of the significant ... -
Modeling Seismic Wave Propagation and Amplification in 1D/2D/3D Linear and Nonlinear Unbounded Media
(American Society of Civil Engineers, 2011)To analyze seismic wave propagation in geological structures, it is possible to consider various numerical approaches: the finite difference method, the spectral element method, the boundary element method, the finite ... -
Analysis of Soil Disturbance Associated with Mandrel-Driven Prefabricated Vertical Drains Using an Elliptical Cavity Expansion Theory
(American Society of Civil Engineers, 2010)The installation of mandrel-driven prefabricated vertical drains and resulting disturbance of soft saturated clays are analyzed with a new elliptical cavity expansion theory. This formulated theory accounts for a concentric ... -
Time Series Prediction of Chimney Foundation Settlement by Neural Networks
(American Society of Civil Engineers, 2011)Neural network (NN) models for time series forecasting were initially used in economic fields. In this paper, NN models for time series forecasting are introduced for use in forecasting the settlement of chimney foundations. ... -
Finite Element Analyses Applied in Design of Foundations and Anchors for Offshore Structures
(American Society of Civil Engineers, 2011)Offshore structures for oil and gas exploitation are designed to accommodate severe environments with large cyclic loads. These structures are either founded directly on the seabed, or they are moored to anchors installed ... -
Three-Dimensional Field-Scale Coupled Thermo-Hydro-Mechanical Modeling: Parallel Computing Implementation
(American Society of Civil Engineers, 2011)An approach for the simulation of three-dimensional field-scale coupled thermo-hydro-mechanical problems is presented, including the implementation of parallel computation algorithms. The approach is designed to allow ... -
Critical Review of the Methodologies Employed for Soil Suction Measurement
(American Society of Civil Engineers, 2011)Modeling the behavior of unsaturated soils necessitates the measurement of soil suction and the establishment of its variation with the water content, which is commonly known as the soil-water characteristic curve (SWCC). ... -
Study of Caprock Integrity in Geosequestration of Carbon Dioxide
(American Society of Civil Engineers, 2011)The Industrial Revolution has led to a substantial increase in the emission of greenhouse gas (GHG) such as carbon dioxide ( -
Stability of Shallow Tunnel Using Rigid Blocks and Finite-Element Upper Bound Solutions
(American Society of Civil Engineers, 2010)Two methods of upper bound solutions were used to calculate the needed support pressure -
Nonisothermal Multicomponent Reactive Transport Model for Unsaturated Soil
(American Society of Civil Engineers, 2011)A multicomponent reactive transport model, coupled with an existing thermal, hydraulic, and mechanical model for porous media, is investigated. The model is based on conservation of mass/energy principles for the flow and ... -
Rock-Joint Micromechanics: Relationship of Roughness to Closure and Wave Propagation
(American Society of Civil Engineers, 2011)The closure behavior of rock joints is intimately related to joint roughness. Here we utilize a micromechanical approach that explicitly considers asperity interactions on joint surfaces to study the rock-joint closure and ... -
Modeling Borehole and Perforation Collapse with the Capability of Predicting the Scale Effect
(American Society of Civil Engineers, 2011)In this paper the writers examine a borehole failure model that is based on fracture mechanics and layer buckling theories and compare its predictions with experimental data. The model assumes that the main failure mechanism ... -
Failure Mechanisms of Pile Foundations in Liquefiable Soil: Parametric Study
(American Society of Civil Engineers, 2010)This paper presents the response of piles in liquefiable soil under seismic loads. The effects of soil, pile, and earthquake parameters on the two potential pile failure mechanisms, bending and buckling, are examined. The ... -
Consolidation beneath Circular Skirted Foundations
(American Society of Civil Engineers, 2010)The effect of foundation embedment on consolidation has not been considered previously in a systematic manner, although this is of particular interest for offshore foundations, where embedment is provided by skirts that ... -
