<p>A method of temporarily supporting a soil mass (12) susceptible, to slide at a scarp slope (13) bounding the soil mass (12) includes advancing a supporting wall (29) in an advancing direction (D1) along the scarp slope (13); and, in addition to the movement in the advancing direction (D1), also moving a surface portion (32), in direct contact with the soil mass (12), of the supporting wall (29), so as to minimize friction between the soil mass (12) and the supporting wall (29).</p> |
