Dimensioning of nailed walls

Motorway A13 - Buchelay (78)

Client :                               NGE FONDATIONS 69

Contracting authority :   CU GRAND PARIS

Prime contractor :            SCE

SOL SOLUTION has been commissioned by NGE Fondations 69 to carry out a G3 type geotechnical study, Study phase, as part of the construction of two nailed walls for the development of the "Les Aureines" and "Les Graviers" business parks in the town of BUCHELAY (78).

A "right turn" lane is to be built under the east span of a crossing structure between the two business parks. On the west side of the structure, a soft lane (for pedestrians and cyclists) must also be created.

These two improvements involve stiffening each of the two bored holes located under the structure.

The supporting calculations have been carried out in accordance with the regulations in force (Eurocodes, national application standards, Clouterre1991 and Additif2002).

In addition to the classical dimensioning of the 2 walls, Sol Solution carried out a modelling under Plaxis® for the precise estimation of the displacements.
