Secondary title:	One dimensional consolidation with strain - dependent material properties
Secondary abstract:	Since the characteristics of soil compressibility are not constant with depth, the main purpose of the thesis was the calculation of the settlements and their development during the consolidation process with strain-dependent material parameters (nonlinear parameters in short). To simplify the task only wide spread load was used for calculations. We focused mainly on comparison of the consolidation times, calculated with constant and with nonlinear parameters. To verify the AJDA code which was developed for the purpose of this thesis, several comparisons of the calculated compression curves were made to the existed code CONDES0 (Yao, Znidarcic, 1997). Because of the different material model used in both codes the overconsolidation pressure and swelling constant were suitably modified to obtain the agreement of the calculated compression lines. According to expectations the compression lines obtained with the above mentioned codes did not fully fit the oedometer measurements in the first load step, while in next load steps a satisfying agreement was obtained. A comparison of the calculated and measured response was performed for the test embankment on Ljubljana marshland and comparable settlements were obtained. On the basis of the presented calculations and comparisons to other computer codes and the performed measurements we can conclude that the AJDA code is suitable for the calculation of the consolidation settlements and their development during time for constant as well as for the nonlinear parameters. The main difference between these two calculations is the required time period of the consolidation process. In average the calculated time with the nonlinear parameters is approximately half of time calculated with the constant parameters.
