Static loads in buried pipe

Applies to land pipe. This pipe is not under internal pressure, but must comply with requirements under static load for maximum deflection to an oval shape, and must withstand buckling, which means a kidney-shaped collapse. 

Calculate vertical deformation of pipe, 6 from relative stiffness of soil and pipe, Rg
