Instability and stabilization of an embankment on the Irbid–Amman Highway in Jordan

Abstract

This paper includes a summary of a geotechnical investigation of an embankment site at station 47 + 300 along the Irbid–Amman Highway in Jordan. The embankment suffered instability problems. This study includes geological and geotechnical mapping of the study area as well as determination of the engineering properties of the various materials encountered at the site.Stability analysis is carried out for the original embankment to explain the failure mechanism, assess the condition at the time of failure, and evaluate the soil parameters for use in stability analysis of remedial measures. Stability analysis is carried out for remedial works. Recommendations are suggested to stabilize the sliding area and to repair the road traversing this landslide zone. Key words : slope stability, embankment, remediation.
