Abstract
This contribution describes centrifuge and numerical studies conducted by the authors to establish the seismic behaviour of micropiles. The authors conclude that micropiles can offer improvements in the behaviour of structures founded on liquefiable soils.
In this discussion, we would like to emphasise two major factors that can influence the behaviour of micropiles. First, micropiles can suffer from instability due to their slenderness following liquefaction of the surrounding soil. Second, excess pore pressure edistribution can cause the soil within the pile group to suffer liquefaction, almost as quickly as that in the free field. Both of these effects have been experimentally observed at the University of Cambridge.
