Modeling the surface element and support system in deep excavation pits and
investigating the deformation mechanism is an important issue. In this study, alternative
solution methods for an anchored bored pile model are compared and discussed, and it is
aimed to contribute to the studies to be carried out in the deep excavation area. A
numerical analysis of retaining wall design is examined in the case of the Sivas cultural
center building's deep excavation using Plaxis 2D and GGU-Retain software. Measured field
data and simulated results are discussed. As a result, the bending moment and lateral
deformation reach a maximum when the foundation pit is excavated to the bottom. It can
be said that the lateral deformation value found with Plaxis 2D is within the allowable
limits, closer to the field data, and provides sufficient quality. The research results will
provide theoretical and practical knowledge for designing and constructing similar deep
excavation pits for the optimal strategy.
