Retaining Wall Friction Angle in 'At Rest' Condition
Retaining Wall Friction Angle in 'At Rest' Condition
(OP)
Hi,
I am designing a timber pole propped cantilever retaining wall for the 'At Rest' condition. For a static/long-term analysis, what wall friction would we expect? For an active case I would usually use 1/3 to 2/3 of the soil internal angle of friction, but for the at rest case there is (notionally) no relative movement between the wall and the backfill. Does this prevent wall friction from being mobilised?
Thanks in advance for the help.

All thoughts appreciated.
@PEinc - By propped cantilever I am referring to a cantilever wall that has been tied back at the top (e.g. by bending the reinforcement in a block wall into the topping slab over the backfill).

I would check the wall as cantilever as a temporary condition during construction. It may be a propped cantilever after the slab is in place for seismic loads and other loads which may occur after the slab is in place, but seems soil loads should be checked in cantilever condition due to construction sequencing.

Order of construction would play into this calculation also as noted above.
