Project Stories | Deep excavation in a sloping site for the assessment of induced ground movements

2020.04.20

About Project

 

The teams of Soletanche Bachy and Vinci Construction France have performed a whole range of geotechnical work to build in Monaco a tower 170 m high, with 10 underground parking levels. This project, carried out on steeply sloping land, began with the execution of an asymmetric excavation 42 m high, to clear the land area for the tower and construct the tower foundations and the parking lot enclosure. This project, carried out to a very tight schedule, is subject to very severe geological, architectural and logistic constraints.

The great height of the tower, and the resulting actions on the foundation under the influence of wind and earthquake, require close liaison between the school and those of the tower of supports. It is difficult to allow the establishment of a single model sufficiently refined to account for the stresses in the structure and in the support given a constitutive law elastoplastic ground. Therefore, they built a geotechnical 3D finite element model, to account for the behavior of land and retaining walls.
