This training supplies the tools needed to describe and apply the workflow for dynamic analysis in FLAC3D, demonstrating a comprehensive understanding of each step involved, including model setup, boundary conditions, input signal application, and damping, to effectively analyze dynamic behavior in geotechnical simulations.
Version Notes:FLAC 8.0
Level: Advanced Runs in Demo: No
A circular lined tunnel is constructed in saturated ground. The ground is dewatered during construction. The tunnel is supported by a temporary shotcrete liner, which is installed while the tunnel excavation is advanced. A final cast-in-place concrete liner is then constructed. The water level is then returned to the original level. The analysis determines the forces and moments that develop in the concrete liner when the water level is returned to the original level, and when the temporary shotcrete liner loses strength.
