摘要： A method of temporarily supporting a soil mass susceptible to slide at a scarp slope bounding the soil mass includes advancing a supporting wall in an advancing direction along the scarp slope; and, in addition to the movement in the advancing direction, also moving a surface portion, in direct contact with the soil mass, of the supporting wall, so as to minimize friction between the soil mass and the supporting wall.
