Example 22: Settlement calculation under flexible foundation of an ore
heap
Description of the problem
In many cases, it is required to determine the settlement
under an embankment, a metal plate foundation of a liquid tank, loads on small isolated plates
or a raft of thin thickness. In these cases, the foundation will be assumed as flexible
foundation.
The Figure shows an ore heap on thin concrete pavement slabs.
The pavement slabs are connected with each other by movable joints. Consequently,
the pavement slabs are considered as completely flexible foundation. The unit weight of the
ore material is γ = 30 [kN/m3].
The foundation base under the ore heap has the dimension of
13*13 [m2
], while the top area of the ore heap has the dimensions of 9*9 [m2].
The height of the ore heap is 4.0 [m] (Figure a).
It is required to determine the expected settlement due to
the ore heap.
