Generalized Nonlinear Softening Load-Transfer Model for Axially Loaded Piles
(American Society of Civil Engineers, 2017)This paper presents the derivation of a generalized nonlinear softening load-transfer model to analyze the load-settlement response for a single pile subjected to axial loading. The model requires the calculation of a ... -
New Insight into Developing Mathematical Models for Predicting Deformation-Dependent Lateral Earth Pressure
(American Society of Civil Engineers, 2017)All existing mathematical models for predicting deformation-dependent lateral earth pressure assume the at-rest state as the turning point for the relationship between lateral earth pressure and soil deformation. However, ... -
Discontinuum Modeling of Solid Deformation Pore-Water Diffusion Coupling
(American Society of Civil Engineers, 2017)This paper presents a numerical scheme for a solid–fluid coupled discrete-element method (DEM) that takes into consideration solid deformation and pore pressure generation and dissipation. Analytical solutions of conventional ... -
Constitutive Model of Granular Soils Using Fractional-Order Plastic-Flow Rule
(American Society of Civil Engineers, 2017)Traditional plasticity models of granular soils are usually established on different loading and plastic potential surfaces. This paper presents a nonassociated bounding-surface model by incorporating a fractional-order ... -
Three-Dimensional Nonlinear Numerical Analysis of Consolidation of Soft Ground Improved by Sand Columns under a Freeway Embankment in Shallow Sea: Case Study
(American Society of Civil Engineers, 2017)The freeway embankment linking Meizhou Island with Putian City in Fujian, China, passes through a shallow-sea area. Sand columns distributed in regular triangles and sand cushions reinforced with geogrids were employed to ... -
Numerical Solution of Single Pile Subjected to Torsional Cyclic Load
(American Society of Civil Engineers, 2017)Large structures, such as offshore platforms, wind turbine foundations, wide buildings, bridges, and railway granular embankments, are often supported by pile foundations. These structures are usually subjected to large ... -
New LGFBG-Based Structural Integrity Evaluation Method for Cement-Grouted Soil Nails
(American Society of Civil Engineers, 2017)This paper proposes a novel optical fiber sensor-based nondestructive method, namely, the long-gauge fiber Bragg grating (LGFBG) method, for integrity assessment of cement-grouted soil nails. This LGFBG sensor was developed ... -
Unified Solution to Drained Expansion of a Spherical Cavity in Clay and Sand
(American Society of Civil Engineers, 2017)This paper presents a novel unified solution to drained expansion of a spherical cavity in both clay and sand. The large-strain theory and a critical state model with a unified hardening parameter are used to describe the ... -
Numerical Evaluation of Consolidation of Soft Foundations Improved by Sand–Deep-Mixed Composite Columns
(American Society of Civil Engineers, 2017)With the development of column technology, a new concept of composite columns has been proposed. Composite columns integrate two columns into one single column, which has a small inner column installed in the middle of a ... -
Stochastic Method for Predicting Risk of Slope Failure Subjected to Unsaturated Infiltration Flow
(American Society of Civil Engineers, 2017)The increase of rainfall and rise of groundwater level can cause frequent failures of unsaturated soil slopes that result in catastrophic landslides. This paper proposes a stochastic method for predicting the risk of failure ... -
