Problem statement: At present study Constant Rate of Strain (CRS) consolidation under Non-Darcy condition was investigated. Approach: In this study a governing conditions on pore water flow were investigated using proposed equation and experimental tests. CRS experiments under different rates of strain were conducted on different soil samples. Results: Results of these experiments and there comparison with proposed equation showed that flow of pore water flow in the most part of each test was Non-Darcy and changed to Darcy condition in the final almost one forth of tests. Conclusion: According to the results the threshold where Non-Darcy flow changes to Darcy was dependent on variations of relative pore water pressure versus total strain and it can be determined based on variations in inclination of relative pore water pressure-total stress curve. |
