ABSTRACT
This paper presents the results of a numerical study carried out to investigate the stability of preloading embankments on the very soft to firm Port-Said Clay deposit in north-eastern Egypt. Characteristic stability assessment charts were developed to predict the factor of safety against deep-seated failure of preloading embankments based on routine field measurements such as the vertical and horizontal displacements. The results were compared with well-established methods. A new chart is also developed in this study to predict the preloading embankment stability based on horizontal displacement measurements at the embankment toe.
