| Abstract | ||||
| The design of deep excavation problems is considered a huge challenge for the designers. Both 2D and 3D modelling are usually considered in the analysis and design. The results of the straining actions including bending moments, shear forces and normal forces as well as forces in lateral supports may differ in case of 2D and 3D analysis. The wall deformation as well as the subsidence profile may also differ in case of 2D and 3D analysis. In this study, PLAXIS 2D and 3D shall be used to assess the adequacy of the software in predicting the site measurements for a case history. The variations in results between both the 2D and 3D analysis shall be also discussed. | ||||
