Abstract

The current research theme is the retaining structures, with special attention to secant pile walls. The deformation of the secant pile wall affects the adjacent building negatively. Accordingly, the overall system rigidity, i.e. capping beam and the piles, should be well investigated and accurately designed. Starting from this perspective, the capping beam lateral rigidity, as wells as its inertia, shape and orientation were covered in details herein. The plaxis 3D is the software used to investigate the above-mentioned design parameters. The pile was modeled by the circular volumetric element with interface element to match the reality as possible. Different excavation shapes were investigated as well as various relative density of the used sandy soil platform. However, several out come have been abstracted and discussed throughout the text body. One of the novel conclusion of this study is; the aspect ratio and shape of the excavated area, showed a sounding effect on the wall behavior and deformation.
