Gabion retaining wall cross section.
The mobilised angle of wall friction δ used in the design should not exceed ϕ 2 where ϕ is the angle of shearing resistance of the compacted backfill.
This will require the foundation soils to be graded and compacted to accommodate for the specified wall batter.

Figure a 1 retaining wall cross section.
Design begins with the selection of trail dimensions for a typical vertical cross section through the wall.
Options prior to enlarging the gabion wall cross section for additional stability is to excavate and bury half of the first course baskets and erect the gabion gravity retaining wall on a 5 6 degree batter towards the retained slope.
Gabion walls may be stepped on either the front or the back soil side face as illustrated.
Going to be building a few of these.

The design of both types is based on the same principles.
The design of both types is based on the same principles.
In order to limit deformation gabion walls should be proportioned in such a way that the resultant force acts within the middle third of the wall s cross section.
