Abstract

The demand for underground space, for use as transport tunnels, parking garages and storage spaces, in many heavily urbanized areas requires the construction of deep excavations in close proximity to sensitive structures. In these situations, accurate predictions of the wall and ground movements are important design criteria in order to avoid damage to adjacent structures. Therefore, a 3D numerical analysis can be valuable to assess the performance of the earth-retaining structure and the surrounding soil. The principal aim of this paper is to study the combined influence of the geometric configurations and the properties of the cohesionless soil on behavior of the diaphragm walls and surrounding soil under static and seismic conditions. In this regard, a 3D numerical analysis is carried out for different configurations of deep excavation in cohesionless soil supported by diaphragm wall. The results show the main impacts of the investigated parameters on the behavior of the earth-retaining structure under static and seismic conditions.
