DESCRIPTION:Soil liquefaction during earthquakes causes a number of engine
 ering problems. This talk will look at the problem of quantifying large st
 ructural settlements and identify a major omission from traditional design
 . Using a combination of field investigation and physical modelling we wil
 l show how design can be improved\, and also demonstrate a rather counter-
 intuitive feature of foundations for large structures. Having then identif
 ied some problems we shall have a look at potential solutions\, paying par
 ticular attention to the novel technique of reinforcing soil with syntheti
 c fibres. The success of these in physical model tests is seen to depend o
 n certain conditions being met that had not been identified by previous wo
 rk using element testing. This opens the door to future investigations in 
 which root structures are explored as potential mitigation against liquefa
 ction.
