            Figure  7.6  Sensitivity  of  geotechnical  parameters  on  crown  settlement  (a)  Elastic
            modulus, (b) Initial horizontal stress coefficient; (c) Cohesion; (d) Internal friction angle.
            Table 7.3 Optimized parameters with changes in the number of measurement points












            determine the most influential geotechnical parameters, the model identification
            process  is  performed  by  the  Akaike  Information  Criterion.  Then  the  parameter
            estimation  process  is  performed  for  all  the  models.  Lastly,  the  reduction  of
            uncertainties by utilizing the EBM is assessed so that the proposed methodology
            is proved to be a means of systematic consideration of uncertainties.
