Numerical Simulation of Long-term Peat Settlement Under the Sand Embankment

On the second step, we simulated the experimental field, which settlement data has being collected more than 23 years. During this period, peat settlement was 1.4-4 m, depending on the thickness of the sand embankment. Input parameters λ*, μ* from the oedometer test were used. The comparison showed the low level of convergence of the settlement-in-time plots with the field data, so the model parameters calibration was required. The correction factors were to be added to the parameters λ* and μ* calculated by the results of oedometer tests.
