Abstract
A facing for an earthwork includes an array of polygonal frames that are connected to the forward ends of stabilizing elements which are embedded in the soil. The polygonal frames are flexibly connected to each other at their corners by joints which allow independent movement of each frame in the plane of the facing without movement in a direction perpendicular to the plane of the facing. Each frame includes a cover which is capable of limited resilient forward movement in a direction perpendicular to the frame and which is capable of resisting the pressure of the soil.
