Abstract : This report presents an analysis of a series of centrifuge earthquake model experiments conducted at Cambridge University, England, on sand embankments incorporating a zone of poorly compacted 'loose' material. The experiments were designated GEM 1 to GEM 6 and were carried out at the Cambridge Geotechnical Centrifuge Centre using the bumpy road earthquake actuator on the beam centrifuge during 1992-1993. In this report, data from the model experiments is reviewed and analysed under a number of key headings: excess pore pressure development, embankment response, natural frequencies and phase differences, and mechanisms of failure.
