Seismic Analysis of Nonhomogeneous Slopes with Cracks Using a Discretization Kinematic Approach
(American Society of Civil Engineers, 2019)In practice, slopes with cracks are very common, particularly in earthquake-prone areas. The slope soil properties exhibit spatial nonhomogeneity because of the geological and environmental effects. This article investigates ... -
Collapse and Swell of Lime Stabilized Expansive Clays in Void Ratio–Moisture Ratio–Net Stress Space
(American Society of Civil Engineers, 2019)The swell-collapse mechanism of residual basaltic clay in both untreated and stabilized with lime conditions was investigated. For treated specimens, the optimum lime content (OLC) was found based on swell potential ... -
Impact of Earthquake Characteristics on Seismic Slope Stability Using Modified Pseudodynamic Method
(American Society of Civil Engineers, 2019)Seismic slope stability analysis is often limited by the ability to encompass specific earthquake characteristics, such as shaking amplitude, frequency, and time as well as varying soil properties, such as cohesion and ... -
Permeability Anisotropy of Loess under Influence of Dry Density and Freeze–Thaw Cycles
(American Society of Civil Engineers, 2019)Loess, a kind of special soil, is widespread in the seasonally frozen soil regions and featured with well-developed joints and pore structure. Notwithstanding, the permeability anisotropy nature of loess can badly impact ... -
Creep Characteristics and Model of Key Unit Rock in Slope Potential Slip Surface
