are connected through a statistical framework that aids in uncertainty quantification and model quality evaluation.First, uncertainty in the estimation of input parameters studies is performed using multivariate information through multiple correlations, in order to determine the parameters that contribute to the uncertainties of the model prediction.From the comparison and statistical analysis, it is found that the estimations by the present method exhibit higher correlations with experimental data than the Tarantino's model for the granular soil samples.The uncertainty of measurement data is analyzed by using the Bayesian method and applied in the estimation of the relative permeability function ( values with smaller uncertainty for the soil with different initial dry densities than the Fredlund and Xing equation.

Site investigation and the interpretation of site data are necessary aspects of sound geotechnical practice.

He was elected Fellow of the Academy of Engineering Singapore (FSEng) in 2012. Phoon received his BEng (First Class Honours) and MEng from the National University of Singapore and his Ph D from Cornell University where his research on reliability-based design has influenced recent codes and specifications, including the 4th edition of ISO2315, (CRC Press/Balkema, 2016). Phoon’s recent research efforts have been directed towards injecting greater realism into geotechnical reliability-based design (RBD), particularly in the characterization of multivariate soil databases and in the development of information-sensitive yet practical RBD that links data explicitly to design. It is easier for engineers to present site investigation as an investment rather than a cost to clients when project needs are complemented by a quantitative notion of “value of information”.

This is arguably the most significant value that RBD brings to current practice.
