Abstract:
In the context of a high-rise building job site, we had to design minimal threshold settlement deep foundations in order to protect the superstructure from differential settlement issues. We therefore successfully designed and built a composite foundation system, mixing a group of micropiles and a laminated elastomeric bearing pad. This article aims to detail the innovative technical solution, to expose the method used to estimate the micropiles settlement, as well as to propose a comparison between the theoretical settlements and the settlements measured during load tests.
