dc.abstract.en<p>Formation of varved clays is characterized by specific compressibility and consolidation features, which are difficult to assess. The construction of an expressway through the area of varved, glacilimnic sediments (Vistula glacial period) required careful analysis of the soil reaction to the increasing load caused by growing embankment. The settlement analyses conducted in relation to the schedule of load increase during construction allowed to verify the deformability assessment of the compressible clays. In order to quantify the compressibility and consolidation parameters of clays, an iterative calculation model was created. The method of the "inverse solution" was used to define optimized values of deformability parameters. The observed delayed reaction of the soil to applied load allowed to assess the nature of consolidation. Comparison of the parameters obtained from the model with the results of laboratory and field tests allowed to evaluate drainage characteristics during consolidation of varved clays as well as to introduce correlation coefficients for interpreting compressibility parameters on the basis of CPT tests.</p>
