Determination of Parameters of Soil Constitutive Models Based on Field Test Data

Iovlev, G. A. / Protosenya, A. G. / Petrov, N. E.

Laboratory soil testing is the main method used to set the parameters of nonlinear constitutive models. However, the sample quality may be too poor to reflect the mechanical behavior of the real soil massif correctly. Additional calibration of the model input parameters based on field test data leads to a more accurate approximation of soil behavior. In this study, methods for automated calibration of input parameters of nonlinear constitutive soil models are proposed. The calculated stress-strain curve for the examined examples showed high convergence with the real one, which proves the correctness and effectiveness of the methodology.
