description: The subject of the graduate qualification work is âOptimisation of soil constitu tive model parametersâ. The scientific objective of this study is a methodology of soil constitutive mod el parameters using SoilTest program. The tasks that were solved during the study: â¢ To form the initial data of the constitutive model by means of laboratory tests modeling; â¢ Optimize the parameters of the constitutive model in various combinations; â¢ Optimize the parameters of the constitutive model, using various combina tions of triaxial and odometer curves as the optimization target; â¢ Optimize the parameters of the constitutive model with different optimiza tion boundaries; â¢ Find an algorithm of parameters optimization, following which the deviation of numerical results from laboratory data is minimized. In the process of work, the method of mathematical modeling employing the SoilTest program was used and a comparative analysis was made. During the research, the initial data were formed, the parameters of the compu tational soil model were optimized in various combinations and with different opti mization boundaries, the relationships between the parameters and the dependence of the result on the optimization boundaries were revealed. Optimization was carried out using various curves as the optimization target and it was revealed which curves should be used to determine the corresponding parameters. As a result, a methodology of soil constitutive model parameters using SoilTest program was found, which makes it possible to reduce the resource intensity of the process of studying the behavior of the soil.
