Numerical Simulation Project:
Simulate a Fixed-ring consolidation test on a clay sample for bath loading and unloading stages using Geostudio Sigma/W package. Assume the following.
Sample diameter: 75mm
Sample Height: 20mm
Bulk Unit weight of the sample: 19 kN/m3
Internal Friction angle: 24
Dilation angle: 0
Module of Elasticity (E): 10MPa
Poisson Ratio: 0.334
Permeability in the satursted condition: 1E-12m/sec
Loading stages: Day 1: 12.5 kPa, Day 2: 25, Day 3: 50kPa, Day 4: 100 kPa, Day 5: 200 kPa
Unloading stages: Day 6: 100 kPa, Day 7: 50 kPa, Day 8: 25 kPa
If you require more parameter, assume a reasonable value and state it in your solution.
|Time (day)||Applied Surcharge stress (kPa)|
|0 (in situ analysis)||0|
Use the following hydraulic conductivity and volumetric water content functions:
Please note that there will be two porous stones at the top and bottom of the sample for providing drainage to the sample.
Therefore, you should add a hydraulic boundary condition of (zero pore-water pressure) to both the top and bottom of the sample.
Note: Make reasonable assumptions if needed and state your assumptions clearly in your report.
Model the above problem using Geostudio 2018 and Prepare a report with the following components:
The report must be submitted in the current MS Word file including the answers to the above questions. You should also upload your GeoStudio into a Google drive and add the link to the report.
