Flow slides of submerged slopes composed of loose sands (10197)

Project nummer: 10197

Omschrijving van het onderzoek

The research programme aims at improving the understanding and modelling capabilities of the hydro-mechanical properties of water saturated loose fine sands. To this end the existing international data bases on the behaviour of granular materials will be extended with experimental data to be collected by means of laboratory experiments on both uniform soil samples and intermediate-scale model embankments, both involving the same sand. The tests on model embankments will give data by which the relevance of each type of soil characteristic for the modelling of the initiation of flow slides of saturated slopes can be evaluated objectively and as such will enable to establish the remaining weaker aspects of the existing types of material models. With this resulting insight as a basis, further material model development will be focussed on particularly eliminating these weaknesses. For the validation of the resulting mathematical and computational models also field data of dredging experiments will be applied. To facilitate the engineering industry, the resulting computational model will also be implemented in the industrial software package Plaxis.
