ABSTRACT
Rigid inclusion is a ground improvement method that has been significantly developed in recent years. Granular load transfer platforms (LTP) are commonly used in this technique leading to an increase in the use of natural resources. In this context, soil treatment can be considered as an alternative solution to use the in-situ soil, improve its characteristics, and limit the pressure on the granular material resources. As part of the national ASIRI+ project, two full-scale tests have been carried out to test the efficiency of treated LTP. An experimental program has been conducted to fully characterize the soil and find the best treatment for the LTP with consideration for the environmental and the economic effects. Then, both tests have been carried out in an 8m x 8m pit with 16 rigid inclusions of 30cm diameter and 1m height. Settlement and stress sensors were installed to monitor the mechanism of load transfer within the platform. Numerical simulation tests have also been performed to better understand the behaviour of the treated LTP.
