Study of big Movement of Temporary Sheet Pile in Elatf Power plant North of Egypt using Finite Element Analysis
Abstract: The failure of sheet pile walls used for temporary works may cause loss of project construction time and money. The failure can be due to lack of knowledge about the soil conditions or a requirement of three dimension analysis, as it may be important for some cases. In this paper a study was made for a big movement during temporary excavation works using sheet pile walls. A back analysis was made using three and two dimensional finite element analysis as well as simple manual calculation in order to find out the causes of the big movement. The results from the analysis was represented and compared with field data and observation. The results from the two dimensional analysis showed higher values than that from three dimensional analysis and both indicated lower results than that from field observation. However the wall movement values deduced from F.E. indicated possible failure. The performed simple manual calculation indicated also failure. The general conclusion was considered that the failure was due to design mistake.
