Three-Dimensional Numerical Modeling of a Piled Embankment
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a three-dimensional numerical modeling of an embankment over a soft ground mass improved by vertical stiff piles, using a finite-difference continuum approach (FLAC3D). Arching occurs in the embankment ...
Multiphase Constitutive Model for the Design of Piled-Embankments: Comparison with Three-Dimensional Numerical Simulations
Publisher: American Society of Civil Engineers
Abstract: This contribution presents a so-called “multiphase” model for soft grounds improved by rigid vertical piles, aimed at capturing the global constitutive behavior of the reinforced ground. A special emphasis is put on the ...
Probabilistic Analysis and Design of Circular Tunnels against Face Stability
Publisher: American Society of Civil Engineers
Abstract: This paper presents a reliability-based approach for the three-dimensional analysis and design of the face stability of a shallow circular tunnel driven by a pressurized shield. Both the collapse and the blow-out failure ...
Face Stability Analysis for a Shield-Driven Tunnel in Anisotropic and Nonhomogeneous Soils by the Kinematical Approach
Publisher: American Society of Civil Engineers
Abstract: The stability on a tunnel face is of great practical significance for safe construction in tunnel engineering. In this work, an advanced three-dimensional (3D) failure mechanism is extended to the face stability analysis ...
Upper Bound Analysis of 3D-Reinforced Slope Stability Subjected to Pore-Water Pressure
Publisher: ASCE
Abstract: Pore-water pressure is a universal unfavorable external force and often poses an adverse impact on reinforced slope stability. Although recently the stability assessment of reinforced slopes has been extended to the ...
Seismic Analysis of Nonhomogeneous Slopes with Cracks Using a Discretization Kinematic Approach
Publisher: American Society of Civil Engineers
Abstract: 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 ...
Three-Dimensional Stability of a Slope Subjected to Seepage Forces
Publisher: American Society of Civil Engineers
Abstract: Three-dimensional (3D) stability of a slope subjected to seepage forces is studied in this work in light of the kinematic approach of limit analysis. The widely used horn model for 3D stability of slopes is presented and ...
Influence of Soil-Arching Effect on Tunnel Face Stability
Publisher: ASCE
Abstract: Based on the slip line theory and the upper-bound limit analysis theorem, a three-dimensional (3D) slip–rupture mechanism to design the shield tunnel face stability is proposed. This model is defined by using a spatial ...
3D Numerical Analysis of a Single Footing on Soft Soil Reinforced by Rigid Inclusions
Publisher: ASCE
Abstract: In the absence of high-quality soils, the rigid inclusion reinforcement technique has been extensively used in geotechnical engineering practice to meet the serviceability requirements of construction projects. This article ...
Behavior of Axially and Eccentrically Loaded Trapezoidal Shell Footings Resting on a Granular Assembly
Publisher: ASCE
Abstract: The objective of this paper is to investigate the behavior of strip shell footings subjected to axial and eccentric loads resting on a cylindrical steel rods assembly that simulates granular soil. An image processing ...
