Deep excavations are mostly prefferred engineering applications to fulfill the need of built-up areas
caused by overpopulation. Depending on the project conditions, it is crucial to provide economical
precautions for excavation safety and to prevent deformation at adjacent structures in terms of
geotechnical engineering. In this study, by using the displacement values of deep supported
excavations, it is aimed to investigate the design and construction performances of deep supported
excavations. In this context, considering the excavation height and deformation relations, the project
and field displacement measurements of 102 sections of 15 deep excavations in and around Istanbul
were examined primarily together with the information gathered from the literature studies. Secondly,
the displacement results obtained from the numerical analyses of deep excavation projects are
compared with field measurements considering the surrounding geological conditions in which the
excavation was made.As a result of these comparisons, it is concluded that the majority of the
investigated excavation projects are quite rigid in terms of displacements, whereas the rate of
excavation projects exceeded the displacement limits is very small (1%).
