Centrifuge modelling of wetting-induced collapse in embankment base

Résumé

The relevancy of the oedometer test used for the prediction of wetting-induced deformations in embankments is examined. Single-and double oedometer tests are carried out. A comparison between laboratory tests and geotechnical centrifuge modelling at 100 × g conducted to examine an inundated embankment made of a sand-clay mixture is made. A 20-cm high embankment model is built and instrumented. The material is compacted on the “dry side” of the optimum Proctor curve at a low compaction rate in order to emphasize settlement phenomena. The inundation simulation is conducted in two successive sequences during centrifuge flight up to a water table of five centimetres. The results prove that the prediction of the dry density after settlement due to inundation is good.
