The Greek Orthodox church of Saint George is one of the most important
archaeological sites in Egypt cultural heritage. This monument exists within the Fortress of
Babylon, a Roman site which dates from 300 AD. Old Cairo has been identified as a core of
activity by Muslims, Jewish, Coptic and Greek Orthodox religions.
Several studies have been previously developed before the elaboration of this restoration
project. These studies were mainly to lower the water table which has been incradibly increased
due to the rapid expansion of population within the vicinity. A dewatering system was
developed and identified as contract 102. This process resulted in several cracks in the structure
main elements especially for the upper recently built part of the church which is in a serious
condition. The vertical cracks in its outer wall, together with the roof and the dome cracks are
the main threaten to the structure overall stability. These cracks initiate a serious safety problem
which may result in a local or even total failure especially if the building is subjected to
unexpected load conditions (earthquakes, excessive vibrations as result of explosions or even
under the effect of heavy traffic vibrations).
A quick intervention requires a deeper knowledge for each element of the structure and accurate
investigation to develop an appropriate technique for repair and strengthening. The accurate
investigation is a key element for successful intervention. The present study is based mainly on
an accurate system of investigation, monitoring and data collection required for computer
modeling. The computer modeling is the key element for applying a successful structural
restoration intervention. The study will propose a method of analysis able to interpret and to
forecast the observed damage and collapse modes. |
