Vertical component on each pile in Row D 291.030.3 260.7 kN

Vertical component on each pile in Row E 291.091.0 200.0 kN

Vertical component on each pile in Row F 291.0151.7 139.3 kN

Checking: 6(442.6382.0321.3 260.7200.0139.3) 10 475 kN, and the

calculation is thus correct.

Example 6.7

A tower is to be constructed on a site where 6 m of very soft clay overlie a very stiff glacial
clay (undrained shearing strength 190 kN/m^2 ). The tower and its base slab weigh 30 000 kN,
