Does anybody have a design method for designing heel blocks? They have different names in different parts of the world, but in the New York City area a heel block is a concrete block which supports a raker which in turn supports a temporary wall.
The problem is that heel blocks seem to be able to support much greater loads than either analyzing them as passively loaded retaining walls or a footings carrying an eccentric, inclined load would indicate. I suspect that the reason that heel blocks can carry a much greater load is that the rakers may constrain the heel blocks to rotate downward into the ground towards the temporary wall, whereas assumptions mentioned above allow heel blocks to move anywhere they want to.
If you have any suggestions, I would appreciate it. Thank you for your responses.
