Design of a large soil retaining structure with pressuremeter analysis Available to Purchase

The A49 motorway runs along the Isère river near Tèche, between Grenoble and Valence, in France, and a large retaining wall was needed there. This structure is an anchored wall, and its design was made with the help of pressuremeter measurements. The pressuremeter tests were carried out with a lantern probe, which was pushed into the soil by dynamic driving. A new pressuremeter theory was used to determine the internal angle of friction of the gravels. The results allowed the best adjustment of the wall to the geotechnical environment. The A49 motorway has been used since 1991 without trouble.
