Anchored Retaining Walls

Anchoring Retaining Walls

Anchored Retaining Walls are very commonly used and are not different in their construction about the others. They are used in moderate height (up to 12.0 m) depending upon the site and soil conditions.

This type of retaining walls is supported by (1) horizontal steel tie rods with isolated anchorage or deadman (fig a), (2) steeply raking tie rods connected to soil anchors or driven steel H piles (fig b). (3) Horizontal tie rods connected to A- frame anchorages with backward and frontward raking bearing piles (fig c).

One end of the cable is attached to the wall and the other is anchored in stable structure like deadman. As the other types, anchored walls should be designed to resist bearing capacity failure as they are often thin walls. The way of driving the piles on the soil depends on its condition, as example if the soil was rock it needs driller and if it was clay the piles can be shot in position by such equipment like air compressor.
