Abstract
At present study constant rate of strain (CRS) consolidation under Non-Darcy condition was investigated. In this study a governing conditions of drainage pore water were investigated using proposed equation. The CRS experiments under different rates of strain were conducted on different soil samples. Results these experiments and there comparison with proposed equation showed that flow of pore water drainage in the most part or each test was Non-Darcy and changed to Darcy condition in the final one forth of test. According to the results the threshold that Non-Darcy flow changes to Darcy is 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.
