ABAQUS 2018 – 3D Soil Vibration Model with Borehole Isolation (M.Tech Project)

I need a 3D numerical model in ABAQUS 2018 for an M.Tech project.

The objective is to evaluate vibration attenuation using borehole isolation and calculate Amplitude Reduction Factor (ARF) at foundation level.

This is a simplified academic model. It should be clear, stable, and suitable for viva explanation, not an overly complex simulation.
Scope of Work
• 3D soil domain with layered properties
• Dynamic analysis (time-history or harmonic)
• Two cases:
1. Without borehole isolation
2. With borehole isolation
Geometry Details

Soil Domain
• Depth: 20 m
• Finite domain: 50 m diameter
• Outer boundary: 80 m diameter (infinite/absorbing boundary)

Foundation Block
• Size: 0.75 m × 0.75 m × 1.0 m
• Position: center
• 0.5 m above ground and 0.5 m below ground

Borehole Isolation
• Arrangement: semi-circular
• Radius from center: 1.8 m
• Number of boreholes: 7
• Diameter: 0.4 m
• Clear spacing: 0.4 m
• Boreholes to be modelled as voids (cut from soil)
oundary Conditions
• Bottom: Fixed
• Outer region: infinite elements or absorbing boundaries
• Top: Free surface
Loading
• Dynamic vertical load (harmonic or time-history)
• Real vibration data available (can be used if required)
Outputs Required
• Velocity time history at foundation
• Peak Particle Velocity (PPV)
• Comparison:
• Without isolation
• With borehole isolation

Final Result:
• Amplitude Reduction Factor (ARF)

Deliverables
• ABAQUS 2018 (.cae file mandatory)
• ABAQUS .inp file
• Screenshots:
• Geometry
• Mesh
• Boundary conditions
• Results
• Short explanation note (1–2 pages)
