Segmental Retaining Wall with Zero Batter
Segmental Retaining Wall with Zero Batter
(OP)
Our Client a developer requires a retaining wall at a site where the grading height of the wall is about 7.5m (24ft) typically i have seen Segmental Retaining walls with a batter (a setback)in this case the setback causes about approx 1.0m(3.0 ft) of costly real estate land being sacrificed. My question is there a possibility of building these walls completely vertical almost 7.5m high using geogrid reinforcement.
The first thought i get is these walls being classified as flexible structure the blocks will shift relative to vertical plane as we compact the reinforced fill i am concerned if it would create a lean in opposite side when active earth pressure fully mobilized. Also, my other worry is differential settlement.
Thanks for suggestions.

You probably will be using a flexible fabric periodically, so the backfill will progress with the wall construction.
The 24' height does not seem impossible for a good unbattered system, but it may be more costly than a bettered system. For much higher walls there is a good record and engineering justification, although much of it is in many countries where the products are produced.
SRWs are a flexible system/structure.
