</TO-DETERMINE>
The consolidation settlement under the corner of mat foundation is
Given information:
The length of the foundation is
The width of the foundation is
The depth of the foundation
The load value Q is
The preconsolidation pressure
The depth values are
Calculation:
Find the consolidation settlement at the center of the foundation using the relation.

Find the net load per unit area using the relation.
At the top of the clay layer,
Refer Table 6.4, “Variation of influence value I”
Take I value as 0.242 for
Find
At the middle of the clay layer,
Refer Table 6.4, “Variation of influence value I”
Take I value as 0.226 for
Find
At the bottom of the clay layer,
Refer Table 6.4, “Variation of influence value I”
Take I value as 0.201 for
Find
Find the average stress increase in the clay layer below the corner of each rectangular area.
