Geotechnical Design and Design Optimization of a Pile-Raft Foundation for Tall Onshore Wind Turbines in Multilayered Clay
(American Society of Civil Engineers, 2018)Although the pile-raft foundation is preferred for supporting a tall wind turbine, the geotechnical design and selection of suitable design parameters are based on a complex procedure. Except the foundation, all the other ... -
Nonlinear Consolidation Analysis of Natural Structured Clays under Time-Dependent Loading
(American Society of Civil Engineers, 2018)Numerous nonlinear theories of consolidation for clay soils have been proposed in the past. Most of them are based on constitutive models of clays whose structural property is neglected, yet the natural structured soils ... -
Analysis of Expanded Radius and Internal Expanding Pressure for Undrained Cylindrical Cavity Expansion
(American Society of Civil Engineers, 2018)Solutions for cylindrical cavity expansion have been studied widely in many aspects, but the analysis of expanded radius and internal expanding pressure is rarely found. In practical engineering, it is of great significance ... -
Semi-Analytical Solution to One-Dimensional Consolidation for Unsaturated Soils with Exponentially Time-Growing Drainage Boundary Conditions
(American Society of Civil Engineers, 2018)This paper presents a semi-analytical solution to Fredlund and Hasan’s one-dimensional consolidation for unsaturated soils subjected to exponentially time-growing drainage-boundary conditions. Two variables are introduced ... -
Analytical Solution for the Consolidation Process of a Stone-Column Reinforced Foundation under Partially Drained Boundaries
(American Society of Civil Engineers, 2018)The consolidation process of a stone-column reinforced foundation under partially drained boundaries was investigated on the basis of a newly developed consolidation theory. An analytical solution was created using a ... -
Numerical Study of Callovo-Oxfordian Argillite Expansion due to Gas Injection
(American Society of Civil Engineers, 2018)An important aspect in an underground radioactive waste disposal project is the characterization of hydrogen production due to steel container corrosion and its migration in the initially water-saturated host rock. For the ... -
Shear Behavior of Rough Rock Joints Reinforced by Bolts
(American Society of Civil Engineers, 2018)The shear response of rock joints under bolt reinforcement is important for supporting the design of a jointed rock mass. This paper aims to investigate the shear behavior of bolted rock joints with different roughness. ... -
Hydromechanical Constitutive Model for Unsaturated Soils with Different Overconsolidation Ratios
(American Society of Civil Engineers, 2018)Overconsolidated unsaturated soils emerge in many engineering problems. This article presents a constitutive model for unsaturated soils using skeleton stress and degree of saturation as fundamental variables. A subloading ... -
Modeling the Impact of a Falling Rock Cluster on Rigid Structures
(American Society of Civil Engineers, 2018)Rockfall is a common geological hazard in mountainous areas and can pose great danger to people and properties. Understanding the impact forces induced by a single rock or a rock cluster on retaining structures is considered ... -
Elastoplastic Coupling Solution of Circular Openings in Strain-Softening Rock Mass Considering Pressure-Dependent Effect
(American Society of Civil Engineers, 2018)Rock-like materials generally manifest both strain-softening and pressure-dependent effects. The critical plastic strain corresponding to the residual state also increases with the confining pressure. In this case, all of ... -
Influence of Intermediate Principal Stress and Principal Stress Direction on Drained Behavior of Natural Soft Clay
(American Society of Civil Engineers, 2018)Drained torsional shear tests were performed on hollow cylindrical intact soft clay specimens to investigate the anisotropic deformation, strength, and noncoaxial behavior in general stress states involving variations in ... -
Evaluation of Rocking and Coupling Rotational Linear Stiffness Coefficients of Adjacent Foundations
(American Society of Civil Engineers, 2018)This paper presents closed-form expressions for rocking spring stiffnesses and coupling interaction rotational spring stiffnesses for a set of closely spaced footings. Substructuring is used to derive analytically the exact ... -
Longwall Mining–Induced Damage and Fractures: Field Measurements and Simulation Using FDM and DEM Coupled Method
(American Society of Civil Engineers, 2018)Comprehensive tests were conducted on a longwall face in China to study mining-induced strata movement and fractures. The first and periodic weightings of the main roof were both captured by microseismic (MS) monitoring ... -
Stability Charts for Rock Slopes Subjected to Water Drawdown Based on the Modified Nonlinear Hoek-Brown Failure Criterion
(American Society of Civil Engineers, 2018)Because of the change in hydraulic gradient of a fully or partially submerged rock slope caused by a drop in the external or internal water level, enhanced seepage forces may lead to slope instability and collapse. Based ... -
Analytical Estimation of the Equivalent Elastic Compliance Tensor for Fractured Rock Masses
(American Society of Civil Engineers, 2018)The elastic compliance matrix is a key parameter for the stability analysis of engineering projects constructed in fractured rock masses. In this study, the energy equivalence and the superposition methods were used to ... -
Stability Analysis of Prescribed Slip Surfaces Based on a Combination of the Equilibrium Equation and the Critical Unstable Condition
