RISTransport Capacity of Overland Flow for Sediment Mixtures
Publisher: American Society of Civil Engineers
Abstract: Sediment transport capacity of overland flows is crucial to understanding and modeling the erosion and deposition processes. The transport capacity for sediment mixtures is particularly complex because of the need for an ...
Transport Capacity of Overland Flow with High Sediment Concentration
Publisher: American Society of Civil Engineers
Abstract: The concept and estimation of sediment transport capacity of overland flows are pivotal to soil erosion, sediment transport, and deposition modeling. There is a limited understanding of the effect of high sediment concentration ...
Stability Analysis of Pressurized 3D Tunnel Face with Tensile Strength Cutoff
Publisher: ASCE
Abstract: The aim of this study is to propose an effective approach to evaluate the stability of a shield tunnel face with tensile strength cutoff by using the upper-bound limit analysis method. Based on the discretization and “point ...
Three-Dimensional Active and Passive Seismic Stability Analysis of Shallow Shield Tunnel Faces
Publisher: American Society of Civil Engineers
Abstract: Comprehensive assessment of the active/passive seismic stability of shallow tunnel faces is an urgent and complex task. This work establishes a promising three-dimensional (3D) approach using upper-bound limit analysis to ...
Novel Approach to Resilient Modulus Using Routine Subgrade Soil Properties
Publisher: American Society of Civil Engineers
Abstract: Gene expression programming (GEP) models, a robust variant of genetic programming, are developed in this study to correlate resilient modulus with routine properties of subgrade soils and state of stress for pavement design ...
Semianalytical Solutions for Elastic–Brittle–Plastic Surrounding Rock under Biaxial In Situ Stress Field Based on Unified Strength Criterion
Publisher: ASCE
Abstract: Semianalytical solutions for circular tunnels under biaxial in situ stress fields are developed in this study. The surrounding rock is assumed to behave as an elastic–brittle–plastic model and is characterized by the unified ...
Three-Dimensional Seismic Bearing Capacity Assessment of Heterogeneous and Anisotropic Slopes
Publisher: ASCE
Abstract: This study proposed an effective approach to accurately evaluate the three-dimensional (3D) seismic bearing capacity of heterogeneous and anisotropic slopes in the framework of the upper-bound limit analysis theorem. An ...
