ABSTRACT

The criterion of the computational model adequacy is the accuracy of fitting the “load-settlement” characteristic obtained with the use of the model with the results of the trial load test carried out within the wide range of loading - from zero to 1.5 times the subsoil load capacity according to the Brauns’conception.The calibration of the computational model involves such an estimation of all the nine parameters of the constitutive models used for description of column material and weak subsoil, to ensure the best fit. The process of optimization is realized in the course of semi-reverse analysis, where some of the parameters are estimated in the laboratory tests and treated as given constant data.
