Railway Surcharge
Railway Surcharge
(OP)
I am designing a soldier pile cofferdam (25'x30' plan dims)directly under some railroad tracks. The tracks will span across the cofferdam on a temporary bridge. There is no question that the full surchage (2000 psf for Cooper E80) must be applied to the sides of the cofferdam that are perpendicular to the tracks. I'm wondering about the sides of the cofferdam that are parrallel to the tracks. Does this surcharge have to be applied to these sides?

Cooper E80 = 80000# / (5' x 8.5') = 1882 psf unless specified otherwise by your particular RR.

RE: Railway Surcharge
As per the parallel loads I agree, though you need to allow for construction surcharge or whatever may be applicable on that side.
