Abstract
The problems of building settlements on port-said area have been a great concern in recent years. Damages occur in buildings due to urban development that requires high rise buildings in such development zones. Raft has been used for many new buildings in port-said . soft to firm clay layers extend down to depths reaching 60 m under the ground surface. This research studies the effect of constructing new building beside an existing one over such soil formation. Differential settlement is crucial in the existing building BL. Two methods are considered in this study to decrease this effect. The first one is constructing R.C. wall between two buildings. The second method is using piled raft as a foundation system in the new building. The typical soil stratification and properties in port-said area are considered.
Parametric study is carried out to examine the influence of the retaining wall and the piled raft variables on the existing building BL. Result revealed that; the retaining wall and the piled raft reduce the settlement under the existing building BL. The study also presents guidelines and diagrams for proposed properties of the retaining wall and the piled raft that may be used in port-said.
