AREMA: Loading Behind Retaining Wall Supporting Tracks.
AREMA: Loading Behind Retaining Wall Supporting Tracks.
(OP)
I am in the process of designing a retaining wall, where a Railroad Track might be added behind it and I wanted to determine the kind of loads I need to add behind the wall. I obtained the following statement from "Manual for Railway Engineering, Volume 2, Structures, AREMA, Not Current Version": 2.2.3 Design Loads, c. Live Load. (2) The axle loads on structures may be assumed as uniformly distributed longitudinally over a length of 3 feet, plus the depth of ballast under the tie, plus twice the effective depth of a slab, limited, however, by the axle spacing.
Would it be possible to check if this is still applicable in the current code? Would providing a 3 feet "high" uniformly distributed infinite load be adequate?
Thanks

I know that I used my Das book for the Strip Loading Eq.

Is the theorethical embankment line,the 2H:1V line shown in the sketch.
If I start my embankment 15'-6" from the center line of the closest track and draw my 2H:1V embankment Sloping down and if this line is below the wall or sheething then I can ignore the surcharge.

I had one more question, say my retaining wall would have fallen within the embankment line (2H:1V), is there a standard depth that if the wall is below that depth, the surcharge can also be neglected?

To me its 2:1 from the bottom of the tie.
What do you guys think?
