Abstract

In the last decades, Deep excavations in populated urban areas had been become a traditional practice. One of the essential for such excavations is to prevent damage to the nearby existing buildings. In order to guarantee the security for the existing buildings and excavation site, it is needed to predict possible problems. In order to evaluate the wall deformation and soil displacements, numerical analyses and empirical methods shall be taken into consideration. In numerical analysis the use of 2D modelling computer programs considered that modelled section is continues infinitely with the same geometry through the perpendicular axis to the section. However, any variation the supporting conditions and stiffness of pit corner in this perpendicular axis effects the behaviour of the deformation. Therefore 3D modelling computer programs provide more realistic solution considering any effect of 3D behavior. In this paper, A 3D analysis computer modeling program PLAXIS 3D is used to study the corner effect on the behavior of the ground deformation around the braced excavation pit. It was found that the deformation decreased when go far from the center of excavation. The corner stiffness has a significant effect on the wall deformation.
