Somebody can help me?

I have HDPE pipe with diameter - 900mm and length - 150 meter lay on the ground. I create the material and turn on Bourdon effects for PE pipe.
The question is how i input ground friction? May be i need use the Underground pipe moleler (but the pipe lay on the ground)?
The pipe have snaking (lateral deflection)when temperature increase. And i want to know the value of lateral deflection when pipe is guided.
What the right way model this situation?

Thanks,Oleg
