Summary :
The A49 motorway runs along the Isère River near Tèche, between Grenoble and Valence in France and a large retaining wall was needed. It is an anchored wall. The design was made with the help of pressuremeter measurement. The pressuremeter tests were done with lantern probe, which was pushed in the soil by dynamic driving. A new pressuremeter theory was used to determine the internal angle of friction of the gravel.
The results allowed the best adjustment of the wall to the geotechnical environment. The A49 motorway has been used since 1991 without trouble
