Abstract
A series of static penetration tests of trapezoidal walls in dense Fontainebleau sand were performed in the geotechnical centrifuge at Gustave Eiffel University. The models of wall with three different shapes (straight profile with thickness D=16mm, 0.75 degree and 1.5 degree of taper angle) but with the same volume were used. The soil mass was instrumented with five stress cells located at two levels at 2D, 4D and 6D distance from the wall axis to follow the stress state changes during the model penetration. Moreover, three pressure sensors were integrated on the model surface to track the changes of normal stress during the continuous penetration of the wall. Thus for the three walls of different geometry the evolution of the following variables is considered during monotonic penetration of the wall: 1) total vertical force; 2) horizontal stresses in the soil mass; 3) normal stresses on the wall surface.
