To reduce the number of erection works for pressure-receiving plates and anchor rods by lengthening the intervals of the installation of the pressure- receiving plates by dispersing and distributing ground reaction from the pressure- receiving surfaces of the bases of the pressure-receiving plates, and to reinforce grounds at positions where the anchor rods cannot be executed by changing the direction of reaction.

In the pressure-receiving plate 1 being installed at the head section 2a of an anchor rod 2 inserted and borne up to a stabilized ground in a ground, applying pressure to the ground and reinforcing the face of a slope (a), the angle of the pressure-receiving surface 3 of the base of the pressure-receiving plate 1 is changed and formed in a projecting shape towards peripheries from a center.
