           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 )
