Soil Treatment By Vibroflottation – Application To Protection Structures Of Djendjen Port, Jijel, Algeria



Auteurs : Khelalfa Houssam .

Résumé

Soil treatment by vibroflotation is a recent technique for improving soil with poor geo-mechanical properties. In addition, this treatment minimizes the risk of liquefaction and the instability of the caisson. This work allows us to establish a two-dimensional numerical simulation of a real vibroflotation test, based on our model and our hypothesis of modeling this mechanism in finite elements. On the other hand, the work consists in making a two-dimensional numerical study of the stability of the caisson carried out on the treated soil, in order to verify its influence on the stability of the structure. The calculation results will be compared with in-situ measurements to validate the numerical model.
