Seismic Active Resistance of a Tilted Cantilever Retaining Wall considering Adaptive Failure Mechanism
(American Society of Civil Engineers, 2019)In this paper, the seismic active resistance of a slanted cantilever retaining wall holding a cohesionless backfill is computed using the method of stress characteristics in association with the pseudodynamic approach. ... -
Active Earth Pressure from Unsaturated Soils with Different Water Levels
(American Society of Civil Engineers, 2019)The problem of active earth pressure has historically been investigated assuming dry or saturated backfills, ignoring the fact that soils are usually unsaturated in nature. This note proposes a kinematic framework for the ... -
Hierarchical Modeling Method for DEM Simulation and Its Application in Soil–Pile–Cap Interaction and Impact Case
(American Society of Civil Engineers, 2019)By developing a hierarchical modeling method, using discrete element analysis software PFC3D, a discrete-element method (DEM) model can be built and solved more efficiently. In this method, smaller particles are used for ... -
Performance of Geo-Base Isolation System with Geogrid Reinforcement
(American Society of Civil Engineers, 2019)To mitigate earthquake-related damage to buildings, a simple alternative method to conventional base isolation techniques is to provide a geo-base isolation (GBI) system, composed of a scrap tire–sand mixture, between the ... -
Performance of a Deep Excavation Irregular Supporting Structure Subjected to Asymmetric Loading
(American Society of Civil Engineers, 2019)Because of the extreme terrain limitations and heavy traffic in congested urban areas, the supporting structures for deep excavations often undergo an asymmetric loading condition at two sides. This article reports the ... -
Geometric Features and Fractal Nature of Soil Analyzed by X-Ray Microtomography Image Processing
(American Society of Civil Engineers, 2019)One of the most basic topics in soil mechanics is the geometrical features of the particles and the soil arrangement. Although these features are of high relevance, many definitions and processes used to evaluate them are ... -
Critical State Study of Natural Silty Sand Instability under Undrained and Constant Shear Drained Path
(American Society of Civil Engineers, 2019)The prefailure instability of the granular soil slope due to lateral stress relief under the drained condition has been investigated experimentally under the constant shear drained (CSD) path in the literature. However, ... -
Impacts of Drying-Wetting and Loading-Unloading Cycles on Small Strain Shear Modulus of Unsaturated Soils
(American Society of Civil Engineers, 2019)The small strain shear modulus (Gmax) is an important parameter in geodynamic problems. To predict the Gmax of unsaturated soils that are normally subjected to complex drying and wetting processes, the effect of hydraulic ... -
New 3D Analytical Solution for Modeling Transient Unsaturated Flow Due to Wetting and Drying
(American Society of Civil Engineers, 2019)This study presents a novel three-dimensional (3D) analytical solution to the Richards equation, which takes as a basis a linear unsaturated model that was previously proposed. Specifically, the partial differential equation ... -
Seismic Active Earth Pressure for Soils with Tension Cracks
(American Society of Civil Engineers, 2019)It is widely acknowledged that the occurrence of seismic force and cracks will increase the active earth pressure acting on a retaining wall. In this work, a kinematic approach for the evaluation of seismic active earth ... -
Testing and Modeling of Saturated Interfaces with Effect of Surface Roughness. II: Modeling and Validations
(American Society of Civil Engineers, 2019)The data from comprehensive interface simple shear tests on saturated interfaces, presented in Part I of this paper, were used to calculate the parameters in the disturbed state concept (DSC) model. The resulting parameters ... -
Determination of Viscoelastic Properties of Soil and Prediction of Static and Dynamic Response
(American Society of Civil Engineers, 2019)This paper employs a general and direct method to determine the time-dependent stress–strain behavior of soil using a Prony series parameter fitting. The rheological stress–strain data obtained from the relaxation test of ... -
