Load acting on a buried pipeline (Marston formula)

¡Ý Cover depth (height from the top of pipeline to the ground surface level) = 1m in principle

¡Ý Load acting on pipeline

W = C©û* ¥ã * B©÷ (Marston formula)

where,
W : load on pipeline(ton/m)
C©û: coefficient depending on the depth and properties of cover material
¥ã : density of cover material (ton/§©)
B :  width (m) = 3d/2 + 0.3
D : outer diameter of pipe (m)
d : inner diameter of pipe (m)


*** Âü°í¹®Çå[References] ***

W = C©û* ¥ã * (3/2 * d + 0.3)^(2)
