Abstract

This paper describes a case history of a deep cement mixed (DCM) column supported embankment. Field measurements of embankment settlements were significantly greater than predicted during the de-sign stage, indicating that the DCM columns were overloaded and yielded. The computed settlement at the base is discussed and compared with field measurements. Results show that there is a good agreement between measured and computed embankment settlement when strain softening behaviour of DCM columns is included. These results clearly show that consideration of strain softening of DCM columns in the analysis is important if yielding occurs during or after construction of the embankment.
