Abstract
In the last three decades, Port-Said city bas been largely developed. This
development requires to replace old low rise buildings (three to four floors) with
higher buildings (nine to twelve floors). However, raft foundation type bas been
used for the most of new buildings in Port-Said. It bas been found due to the
presence of clay layers that settlement bas exceeded the allowable value and caused
problems for the new building itself as well as damages for the surrounding old
buildings. This thesis searches for another foundation system that overcomes
settlement problem in Port-Said. Piled raft and pile group foundation types have
been studied in the thesis as settlement reducers. For achievement of the task, the
new reclamation areas in Port-Said were subdivided into six major zones. In each
zone typical soil stratification and properties were considered. Back analysis has
been carried out to verify the soil parameters used 4t the study. Parametric study has
been carried out to examine the behavior of single pile, pile groups, raft and piled
raft on the six zones under different variables and• conditions. Both linear and
nonlinear behaviors have been taken into account when analyzing foundation
elements. Results revealed that pile foundation is a good suitable foundation system
in Port-Said city comparing with raft. The study bas presented guide lines and charts
for piled raft that may be used in Port-Said.
