Live Load vehicle 102 K per axle
(OP)
I just had a question about how to do a live load calc. for a pipe with an axle load of 102,000 pounds. Has anyone else seen this size load? The project is in CA. Maybe to take into account earthquake? Seems like a very heavy vehicle. This wa not an aiport but I-5.

To answer your question, I would use elastic layer analysis to get the stresses on the top of the pipe.

I would verify the loads and axle configuration (I seriously doubt that 102K is supported by a single axle). Current design loads for roads and bridges are for 16K axle loads. There are various other "permit" and military vehicle load that can be accounted for, but my guess that 102K axle load vehicle would not even be allowed to get a permit for use on any interstate highway (I am not familiar with I5). So as the others have suggested the first step is to verify the load, as it appears to be way above and beyond any design criteria for typical bridge and pavement design.

This may not apply to the "pipe" in question, but that second part can be important sometimes.

So a heavier (higher capacity) hydro crane could concievably reach the axle loads you are being relayed.
For normal travel, many parts and pieces are shipped on supporting rigs and secondary axles are employed, but when it is all rigged up, it is heavy with two axle groups.
So it would seem the scenario is possible, but it should surely be possible to find a more manageable construction plan.
When working with the 200 ton crane, the crane drove to its setup location stripped bare for highway/street travel and was assembled my a "helper crane" to get rigged for the big pick.
If the load is what it is, this may not relate, but loads of that magnitude are not out of the realm of possibility for fairly standard construction equipment (200 ton is not all that big cranewise - still half your axle load).
