Which wall type uses a deadman or expanding anchor to resist stresses from the backfill?

The anchored wall type is specifically designed to utilize deadman or expanding anchors to provide additional support against the stresses exerted by backfill material. When backfill is added to the wall, it generates considerable lateral earth pressure. In order to counter these forces, anchored walls incorporate anchors that extend back into the soil behind the wall, effectively stabilizing the structure and preventing it from tilting or failing under the load.

Deadman anchors are buried in the soil and hold the wall in place by creating a counterbalance against the pressure of the backfill. Expanding anchors can increase their grip within the soil as they expand, further enhancing stability. This method is particularly useful for maintaining wall integrity in situations where traditional means of support may not suffice due to the height or weight of the backfill.

Other wall types may use different methods or materials for stabilization but do not typically utilize deadman or expanding anchors in their design, which distinguishes anchored walls as the most effective choice for addressing the specific stresses from backfill.
