Numerical Procedure for Simulating the Two-Phase Flow in Unsaturated Soils with Hydraulic Hysteresis
(American Society of Civil Engineers, 2016)When modeling the seepage process in a variably saturated porous medium, it is crucial to properly characterize the effects of hydraulic hysteresis. In this paper, a theoretical model of two-phase flow in porous media is ... -
Numerical Analysis of Earth Embankment Resting on Liquefiable Soil and Remedial Measures
(American Society of Civil Engineers, 2016)Liquefaction-induced ground displacements resulting from earthquake shaking are a major cause of damage to earth structures comprised of, or underlain by, loose saturated granular soils. The present paper describes the ... -
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 ... -
Anomalous Data Detection for Roller-Integrated Compaction Measurement
(American Society of Civil Engineers, 2016)This paper presents a theoretical and experimental analysis of an anomalous data detection treatment for roller-integrated compaction measurement (RICM) data. Anomalous data, which may be discovered during the collection ... -
Numerical Modeling of Suction and Trench Formation at the Touchdown Zone of Steel Catenary Riser
(American Society of Civil Engineers, 2016)Steel catenary risers (SCR) are widely used in deepwater oil and gas production. The riser–seabed–water interaction near the touchdown zone is one of the main concerns in the design of fatigue life of SCR. During upward ... -
Vertical Uplift Capacity of Two Nearby Horizontal Strip Anchors Using the Method of Stress Characteristics
(American Society of Civil Engineers, 2016)The present study addresses the effect of interference on the uplift capacity of two closely spaced horizontal strip anchors embedded in cohesionless soil. The analysis has been performed using the method of stress ... -
Effect of Clogging on Rate of Consolidation of Stone Column–Improved Ground by Considering Particle Migration
(American Society of Civil Engineers, 2016)Installation of stone columns is one of the most popular ground improvement techniques used to improve the strength of soft soil. Owing to the presence of more pores in the stone column, it acts as a drainage path for ... -
Experimental Study on the Influence of Drillhole Roughness on the Pullout Resistance of Model Soil Nails
(American Society of Civil Engineers, 2016)Pullout resistance of cement-grouted soil nails is a key factor affecting the safety conditions of retaining walls, slopes, and excavations. The mobilized frictional resistance at the interface between soil nails and ... -
Simplified Finite-Element Model for Site Response Analysis of Unsaturated Soil Profiles
(American Society of Civil Engineers, 2016)A numerically stable and computationally efficient finite-element model for analyzing the dynamic response of unsaturated soil profiles in terms of total stresses is presented in this paper. The highly nonlinear, fully ... -
Improving Rockbolt Design in Tunnels Using Topology Optimization
(American Society of Civil Engineers, 2016)Finding an optimum reinforcement layout for underground excavation can result in a safer and more economical design, and is therefore highly desirable. Some works in the literature have applied topology optimization in ... -
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 ... -
Effect of Destructuration on the Compressibility of Perniö Clay in Incremental Loading Oedometer Tests
