Evaluation of Bearing Capacity of Caissons Subject to Scour

Abstract

The construction of any river obstruction has some morphological impacts on the river bed and flow as it implies some disturbance to the river water flow. This disturbance causes local scour to occur due to bridge construction. For many reasons, there exists a need to protect these assets by continuous monitoring and maintenance. For this research, 6 th October Bridge was considered as a case study for bridges constructed on caissons along the River Nile. A field data (contour maps for the bed of the River Nile at year 1982and 2008) and computer model FDOT (developed by Florida Department of Transportation), was used to evaluate the depth of scour at the caissons of 6 th October Bridge. Conclusions and recommendations were highlighted.
