Ground improvement case studies – Chemical lime piles and dynamic replacement

Patrick K. Wong

This paper presents two case studies of soft ground improvement, one involving the use of Chemical Lime Piles for a project in Penang, Malaysia and the other involving the use of Dynamic Replacement in Alexandria in Egypt.

The background and the design approach of each of these ground improvement techniques are presented together with a description of their application in two recent projects. In both cases, field performances are compared with the original designs, and are found to exceed design predictions with respect to strength increase.
