Fellow engineers, I'm designing an underground pipe for Natural Gas (12" - 6" diameter) 800m length. My client asks me to design a solution to protect the pipe for the case of loading a crane-leg above the pipe. He thinks that it could be a 500 t-m crane there. The maximum the crane could apply in one leg is 160 ton and they use a 3.8X2.4m dispersal plate (17.6 t/m²). The pipe depth is varying between 1.5 to 2.7 m. The geotech engineer doesn't collaborate so much; it's a sandy-clay soil (I hope I'll get some more information about the soil bearing capacity and sedimentation properties.) Additionally the client asks to design them without steel reinforcement, in order to avoid problems with the cathodic protection. So I'm looking for a simple way to check the impact of the crane loads on the pipe, and a way to design a plastic reinforced concrete pad to bear this load. I would be glad to get comments and recommendations.
