... ABSTRACT: Uncertainties caused by soil heterogeneity play an important role in the prediction of contaminant migration. A process-based approach is shown as a method to generate better predictions of the contaminant migration in the presence of large uncertainties. The method discussed here...

... and it was used to estimate the insitu stresses in the ground. The measured effective stress in the sample p'k in combination with specific volume vk and the ratio of the cross anisotropic parameters J/3G* enable the prediction of the pre yield stress path during drained shearing. Comparison between predicted...

It was observed that the formulations might be used for small to large strain problems i.e., for inextensible to extensible...

... of judgement is on the model parameter values. The method of predictive analysis is a valuable technique that enhances backanalysis and numerical model predictions. The method forces the analyst to define key events for which the prediction of worst outcomes is required. Predictive analysis determines the set...

...PREDICTION OF FINAL DISPLACEMENT OF TUNNEL SECTION DURING EXCAVATION NY. Kim1, YH. Park1 and SH. Kim2 ABSTRACT Certain points on tunnel section start to displace before measurements begin from within the tunnel. Therefore prediction of final displacement tunnel section during excavation would...

This paper introduces a new hazard assessment, the "viability index" approach, to scale full-span wedge predictions, accounting for both occurrence and instability potential of possible wedge geometries...

...PREDICTION OF DISPLACEMENTS IN TUNNELLING P.J. Sellner1 and W.

Current systems do not have the capacity to make predictions using realistic geological interpretations. Of prime concern to geotechnical engineers is extrapolation, from exposed zones to inaccessible regions...
