Figure 1.4 (A) Heger earth pressure distribution; (B) Olander/Modified Olander
radian pressure distribution; (C) Paris/Manual uniform pressure distribution (ACPA,
1993).
For the case of superimposed load distributed over an area of considerable
extent, the formula for load on pipe is (ASCE No.60, 2007):
W sd 5 C s pFB c ð1:14Þ
where
W sd 5 the load on the pipe (N/m)
2
p 5 the intensity of distributed load (N/m )
