Dilatancy Equation for Rockfill Materials under Three-Dimensional Stress Conditions
(American Society of Civil Engineers, 2019)The intermediate principal stress ratio b has a significant influence on the dilatancy behaviors of rockfill materials. The dilatancy equation is defined as a function of the dilatancy dg and the stress ratio η. To investigate ... -
Factor of Safety of Geosynthetic-Reinforced Slope in Unsaturated Soils
(American Society of Civil Engineers, 2019)Matric suction tends to exert important effects on the stability of geosynthetic-reinforced soil slopes; however, it is usually neglected in the previously published literature. To quantitatively evaluate the increment in ... -
Stability of Unsaturated Soil Slopes with Cracks under Steady-Infiltration Conditions
(American Society of Civil Engineers, 2019)Most classical approaches for evaluating the stability of soil slopes with tension cracks are performed under dry and/or saturated conditions. The suction-induced effect of unsaturated soils is generally neglected in ... -
Effect of Interface Friction Angle between Soil and Reinforcement on Bearing Capacity of Strip Footing Placed on Reinforced Slope
(American Society of Civil Engineers, 2019)In the last few decades, many experimental and a few numerical investigations were performed to investigate the behavior of strip footing placed on the soil slope. However, most of the previous studies were case specific. ... -
Analysis of Rayleigh Waves in Micropolar Thermoelastic Solid over a Dual-Phase-Lag Semi-Infinite Thermoelastic Substrate under Interfacial Imperfections
