<p>The piezocone dissipation test is commonly used to estimate soil consolidation behavior. However, there are challenges in determining the soil consolidation coefficient by this test. One complication is the presence of partial drainage conditions when conducting tests in soils with intermediate permeability. Additionally, non-standard dissipation curves add complexity to the interpretation of soil consolidation behavior. These factors can significantly affect the magnitude of the estimated consolidation coefficient, which needs to be accounted for in the existing relationships. In this study, several series of numerical analyses were employed to determine the soil consolidation coefficient under different drainage conditions. The results of the numerical modeling were verified against the existing laboratory measurements. The variations of excess pore water pressure in the radial and vertical directions of the piezocone were numerically examined at various depths and drainage conditions. A practical approach for estimating the soil consolidation coefficient was proposed, considering the aforementioned limitations. The changes in the soil consolidation coefficient at different depths and penetration rates were investigated, and an updated version of the field decision chart was proposed. The suggested methods offer a reliable estimate of the consolidation coefficient for partially drained soils, which can be applied in geotechnical engineering practice.</p>
