Using the formulae in Annex B.2 for undrained conditions, the length of side of the footing for Case B was 3.75 m while for Case C is was 4.0 m. Hence, as for E2, Case C is critical and B = L = 4.0 m. This may be checked as follows. For Case C, the design vertical action at footing base: Vertical action (Vd) = yG ...

If P/A exceeds M/S, then the maximum bearing pressure equals P/A + M/S and the minimum bearing pressure equals P/A-M/S. 6. If P/A is less than M/S, then the soil bearing pressure is as shown in Fig. 5-1. Such a soil bearing pressure distribution would normally be considered undesirable because it makes the footing structurally ineffective.
WebJul 25, 2024 · Tests must be carried out to determine the bearing capacity of the fill. Generally, fill is unlikely to meet the required bearing capacity so foundations must pass through the fill down to solid bearing below. Water table. A high water table means the water pressure in the soil is high and that the soil is likely to be correspondingly weaker.
