Coupled Bearing Capacity Factor for Strip Foundations on Cohesive-Frictional Soil Slopes under Static and Seismic Conditions
(ASCE, 11/1/2020 )This paper investigates the bearing capacity of strip foundations resting on a cohesive-frictional soil sloping ground under both static and seismic conditions by applying the kinematic theorem of limit analysis. With the ... -
Accumulated Plastic Strain Behavior of Granite Residual Soil under Cycle Loading
(ASCE, 11/1/2020 )In this study, the accumulated plastic strain (APS) of granite residual soil under cyclic loads is investigated by a series of undrained cyclic triaxial tests. Granite residual soil is a special kind of soil that is widely ... -
Experimental Study of Reinforced Layered Rocks with a Hard–Weak–Hard Structure under Compression
(ASCE, 11/1/2020 )The failure mechanisms of unreinforced and reinforced layered rocks with various layer dip angles were analyzed using acoustic emission (AE) activities, failure modes, and load–displacement responses. The results indicate ... -
Modified Duncan-Chang Constitutive Model for Modeling Supported Excavations in Granular Soils
(ASCE, 11/1/2020 )Numerical analyses have been widely used to investigate the stability of deep excavations. The results of this type of analyses rely on the constitutive model that is adopted for the analyses. Although many advanced ... -
Evaluation of Hydraulic Conductivity Functions of Saturated Soft Soils
(ASCE, 11/1/2020 )Hydraulic conductivities of soils rely significantly on three factors, the properties of their pore water, the relative quantity of their pore water, and changes in their pore structure. For saturated soft soils, that ... -
Solutions for One-Dimensional Rheological Consolidation of a Clay Layer with Threshold Hydraulic Gradient under Multistage Loading
(ASCE, 11/1/2020 )For clays with low permeability, some experimental results show that there may exist a threshold hydraulic gradient, below which the water in clays cannot flow. This threshold hydraulic gradient induces a moving boundary ... -
Numerical Simulations of Triaxial Tests on Soil-Root Composites and Extension to Practical Problem: Rainfall-Induced Landslide
(ASCE, 11/1/2020 )Root reinforcement is an interesting and environmentally favorable measure for soil stabilization. When properly applied, it can improve soil strength significantly. The paper presents a simulation of a series of drained ... -
Active Stability Analysis of 3D Shallow Tunnel Face with Longitudinally Inclined Ground Surface Based on Nonlinear Mohr–Coulomb Failure Criterion
(ASCE, 11/1/2020 )The longitudinally inclined (the tunnel excavation direction) ground surface often appearing at the shallow tunnel entrance and exit zone threatens and reduces the tunnel face stability. However, studies on this stability ... -
