Gravel Lateral Pressure for Small Backfill Space
Gravel Lateral Pressure for Small Backfill Space
(OP)
Have a condition where the inside face of a handicap ramp wall is located just 4'-5" from the outside face of building fdn wall. The building fdn wall retains 12'-9". Handicap ramp goes from lower grade to top of building fdn wall (12'-9"). Filling space btwn walls w/ 3/4" clean gravel. Seems to me the distance btwn walls is too small to mobilize full soil wedge so the EFP should be reduced. What EFP should the ramp wall be designed for?

Taking the friction between the wall and the soil may also make a significant difference in this case.
