Anchored walls (‘tieback’ walls)

These are vertical retaining walls supported by an “anchor,” or dead weight, fixed in the ground on the uphill side and tied by a cable, chain or rod, which may be inserted into the ground by boring. The ground anchor is expanded mechanically or may be fixed by the pressure injection of quick-setting concrete, which creates a block set in the soil or rock. Ground anchors must be located beyond the angle of repose of the soil, which is the wall’s potential failure plane.
