Liquefaction of Unsaturated Sands
(American Society of Civil Engineers, 2016)Recent laboratory tests and field observations have revealed that unsaturated sands are susceptible to liquefaction. Systematic investigation of liquefaction potential of unsaturated sands is, however, lacking. In this ... -
Predicting Liquefaction-Induced Lateral Spreading by Using Neural Network and Neuro-Fuzzy Techniques
(American Society of Civil Engineers, 2016)The prediction of lateral spreading is an important task because of the complexities of lateral-spreading behavior. The aim of this work is to improve an accurate liquefaction-induced lateral-spreading prediction by using ... -
Experimental Evaluation and Finite-Element Simulations of Explosive Airblast Tests on Clay Soils
(American Society of Civil Engineers, 2016)This study examined the effects of small-scale airblast experiments on clay soils and compared experimental results with numerical solutions obtained through finite-element simulations. Thirty-three suspended explosive ... -
Thermomechanical Response of Geothermal Energy Pile Groups in Sand
(American Society of Civil Engineers, 2016)The thermomechanical response of geothermal energy pile groups in sand was studied in the present work by using a three-dimensional nonlinear finite-element analysis procedure. A raft was considered on the piles. The ... -
State-of-the-Art: Prediction of Resilient Modulus of Unsaturated Subgrade Soils
(American Society of Civil Engineers, 2016)In this paper, equations that were proposed in the literature over the past four decades to estimate or predict the variation of the resilient modulus with respect to soil suction for pavement base-course materials and ... -
Simplified Procedure for Coupled Seismic Sliding Movement of Slopes Using Displacement-Based Critical Acceleration
(American Society of Civil Engineers, 2016)Downward movement of sliding soil mass in earthquake-induced earth slopes may gradually improve the system's stability. Hence, significant change in critical (or yield) acceleration of the slope is anticipated. The existing ... -
Experimental Analysis of Embankment on Ordinary and Encased Stone Columns
(American Society of Civil Engineers, 2016)This work investigated the behavior of embankment models resting on soft soil reinforced with ordinary and encased stone columns (ESCs). Model tests were performed with different spacing distances between stone columns and ... -
Discrete Element Simulations of Shallow Plate-Load Tests
(American Society of Civil Engineers, 2016)Shallow plate-load tests were simulated using a two-dimensional discrete element procedure together with parameters calibrated from a series of biaxial compression experiments on aluminum rods. The deformation and force ... -
Exact Solution of the Friction Circle Method
(American Society of Civil Engineers, 2016)The modified friction circle method is still an important tool in slope-stability investigations. The theoretical soundness of this method was investigated, and it is shown here that there is theoretical inconsistency and ... -
Uplift Capacity of Anchors in Layered Sand Using Finite-Element Limit Analysis: Formulation and Results
(American Society of Civil Engineers, 2016)The vertical pullout capacity of strip and circular plate anchors embedded horizontally in a layered sandy medium was computed by using the plane strain and axisymmetric lower-bound limit analyses in combination with finite ... -
Constant Water Content Compression Tests on Unsaturated Compacted Soil with Suction Measurement Using a HCT
(American Society of Civil Engineers, 2016)Soil compaction is a process used in different engineering works; from the most complex to the simplest, the quality of soil compaction indiscriminately affects the final condition of the compacted soil in terms of engineering ... -
Love-Type Wave Propagation in an Irregular Prestressed Composite Sandwiched Layer
(American Society of Civil Engineers, 2016)The present problem analytically investigates the possibility of Love-type wave propagation in a prestressed irregular composite layer lying between an upper prestressed heterogeneous isotropic layer of finite width and a ... -
New and Simple Equations for Ultimate Bearing Capacity of Strip Footings on Two-Layered Clays: Numerical study
(American Society of Civil Engineers, 2016)In this paper, two very simple and accurate equations are introduced that enable geotechnical engineers to determine the undrained ultimate bearing capacity of shallow strip foundations resting on two-layered clays. Results ... -
Numerical Analysis for a Realistic Support Design: Case Study of the Komurhan Tunnel in Eastern Turkey
(American Society of Civil Engineers, 2016)The aim of this study was to highlight the importance of the numerical approach in realistic support design for tunneling. The Komurhan Tunnel, which is to be constructed between the Elazig–Malatya highway, located east ... -
Fracture Analysis of Cohesive Soils Using Bilinear and Trilinear Cohesive Laws
(American Society of Civil Engineers, 2016)Tensile cracking of soil is an important issue that affects the strength and permeability of soil in many geotechnical applications, such as in soil dams and landfill liners. When the size of the fracture process zone is ... -
