PARAMETER ESTIMATION USING EXTENDED BAYESIAN METHOD 213
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.
