Rigid Inclusion Systems for Embankment and Building Support: Past, Present, and Future
Rigid inclusion systems have gained rapid adoption for
ground improvement in supporting embankments and
buildings, driven by advantages such as fast
installation, enhanced performance, and cost
efficiency. This lecture will trace their evolution from
early applications to today’s practices, covering types,
installation methods, load transfer mechanisms, and
key design considerations. Topics include performance
under vertical and lateral loading, the role of load
transfer platforms, the need for steel reinforcement,
and applications and issues in settlement reduction,
slope stability, and liquefaction mitigation. This lecture
will also explore emerging research, unresolved
challenges, and innovations shaping the future of rigid
inclusion technology.
