Steel Encasement Pipe thickness Based on Cooper E-80 Loading
(OP)
I have 80 feet of 48" Steel Encasement pipe (SEP) that is to be bored and jacked under a single track railroad. The cover from the bottom of tracks to the top of SEP is approx. 3-3.5ft. Wall thickness of SEP is .688 inches. I need to determine if the SEP wall thickness is sufficient based on Cooper E-80 railway loading. Also need to verify that the pipe cover will sustain railroad loads according to AREMA criteria. SEP is ASTM A139 Grade B. Can anyone steer me in the right direction?

Normally a railroad will not approve 3-3.5 feet. They usually go for MINIMUM 4.5 to 6 feet.
Why so shallow?
What would you be doing, if you knew that you could not fail?
