Abstract: | This paper introduces a formula for the vertical pressure on a buried pipeline by using a modification of the basic assumptions
of Marston’s theory. The fill’s cohesion is considered. The included angle between the slide surface above the pipeline and
the horizontal surface is assumed to be equal to the fill’s angle of friction. The friction is calculated by multiplying the
active earth pressure on the outer column and the coefficient of the friction on the slide planes It was found that the fill’s
cohesion had important influence on the vertical pressure, whose vertical pressureC
c decreases with increase of the fill depth, a relationship according with that observed in practice. At the end of the paper,
the formula is employed to analyze a practical case.
