Résumé / Abstract
An experimental study has been carried out at CERMES on 1 g physical model made up of reinforced soil by a rigid inclusion. Loading tests were conducted at a prescribed rate of displacement by using a rigid disk. The experimental work focused on the effect of thickness and grain size distribution of the mattress material on the load transfer between the rigid inclusion and compressible soil. The variation of cover ratio has been also analyzed and the composition of compressible soil as well. Obtained results indicate the increase of cover ratio from 2.22 % to 8.88 % leads to 100% increase of efficiency and the settlement reduction is 50%. The variation of mean diameter of mattress material from 2.5 mm to 12 mm clearly led to an increase of efficiency equal to 90% and settlement reduction of 25%.
