Abstract
The uncoupled Terzaghi consolidation equation (excess pore pressure only) is widely used to predict the rate and magnitude of settlements in clayey soils. The theoretical solution is based on the approach of considering the soil permeability and compressibility as one parameter obtained by experimental methods – the coefficient of consolidation cv. This article presents two analytical tools that allow us to determine the consolidation coefficient, which is independent of a single measurement point and represents the consolidation behavior for the significant progress of settlements. The presented methods were based on the process of optimizing the coefficient of consolidation value and the quasi-constant approach, which assumes the identification of a quasi-filtration consolidation phase using the log cv - U relationship. To assess the validity of each method, the experimental results were compared to the theoretical solution and quantified using a new statistical parameter dn.
