pipeline

Dear Geoff Stone ,

   thanks for your attention to my problem. this pipeline pressure is 200psi and soil is ML(stiff clayey silt whit some sand).

   what is compaction factor(in autopipe manual is 80% to 94%)usually?    it has more effect on cohesion factor.do you have any guideline for checking of upheaval bucking of buried pipline?   thanks
