Undrained Pore Pressure Prediction in Clayey Soil under Cyclic Loading
(American Society of Civil Engineers, 2015)Prediction of pore-water pressure is important for understanding the behavior of soils under both static and cyclic loading and also for estimation of their effective stresses. Undrained cyclic pore pressure models available ... -
Experimental and Numerical Studies of Circular Footing Resting on Confined Granular Subgrade Adjacent to Slope
(American Society of Civil Engineers, 2016)Many situations exist where foundations must be constructed on or near slopes. As a result, the foundation’s bearing capacity is reduced, and the slope might collapse. This paper presents the results of laboratory and ... -
Potential Method for 3D Wave Propagation in a Poroelastic Medium and Its Applications to Lamb’s Problem for a Poroelastic Half-Space
(American Society of Civil Engineers, 2016)In cylindrical coordinates, a potential method is developed for three-dimensional (3D) wave propagation in a poroelastic medium. By using the proposed potential method, the wave propagation problems can be reduced to the ... -
Practical Method for the Design of Pretensioned Fully Grouted Rockbolts in Tunnels
(American Society of Civil Engineers, 2016)This study develops an analytical approach to quantitatively model the efficiency of the pretensioning of grouted rockbolts in terms of reduction of tunnel convergence. In this study, the distribution of force along the ... -
Effect of Fines on Behavior of Braced Excavation in Sand: Experimental and Numerical Study
(American Society of Civil Engineers, 2016)In this paper, the effect of fine content in the retained sandy soil on the behavior of braced excavation has been studied using experimental and numerical models in terms of four design factors: strut force, bending moment ... -
Influence of Particle Breakage on Critical State Line of Rockfill Material
(American Society of Civil Engineers, 2016)The influences of particle breakage on the position of the critical state line (CSL) were systematically investigated in this paper through a series of large-scale triaxial compression tests on Tacheng rockfill material ... -
Prediction of Safe Bearing Capacity of Noncohesive Soil in Arid Zone Using Artificial Neural Networks
(American Society of Civil Engineers, 2016)Estimation of safe bearing capacity (SBC) of noncohesive soil based on Indian Standard Code requires a lot of field work, viz, conducting direct shear tests to determine cohesion and angle of internal friction, performing ... -
Renovated Comprehensive Multilevel Evaluation Approach to Self-Healing of Asphalt Mixtures
(American Society of Civil Engineers, 2016)Based on fuzzy evaluation and the analysis hierarchy process, this paper develops a method for evaluating the self-healing capability of asphalt mixtures. In developing the method, 18 judgment indicators were selected on ... -
Parameter Study of a New Strut-and-Tie Model for a Thick Cap with Six Piles
(American Society of Civil Engineers, 2016)A comprehensive strut-and-tie model is a function of the nodes, struts, ties, model types, and pile reaction force. Because each element has more than one solution, the function is a problem of permutations and combinations. ... -
Effect of Granular-Column Installation on Excess Pore Pressure Variation during Soil Liquefaction
(American Society of Civil Engineers, 2016)During many earthquakes, soil liquefaction causes dramatic damage. The use of a granular column is a ground-improvement technique used to mitigate soil liquefaction. The present paper studies the performance of reinforcement ... -
Uplift Capacity of Plate Anchors in Saturated Clays: Analyses with Different Constitutive Models
(American Society of Civil Engineers, 2016)Evaluation of the uplift capacity of plate anchors in saturated clay is an important aspect in the design of offshore foundation systems of various structures. In most of the literature reviewed, simple constitutive models ... -
One-Dimensional Coupled Infiltration and Deformation in Unsaturated Soils Subjected to Varying Rainfall
(American Society of Civil Engineers, 2016)Assuming that the water content and hydraulic conductivity of unsaturated soil are exponential functions of the pressure head, Green’s function is used to obtain analytical solutions to one-dimensional coupled rainfall ... -
Effect of Loading Direction on the Response of Laterally Loaded Pile Groups in Sand
(American Society of Civil Engineers, 2016)Previous experimental studies on laterally loaded pile groups usually applied loading along the direction parallel to the edge of the pile cap. This study aims to determine the effects of the loading direction on the ... -
