2. Skempton's Analysis for Cohesive
soils
•Skempton (1951) has showed that the bearing capacity factors in
𝑁𝑐 Terzaghi's equation tends to increase with depth for a cohesive
soil.
For (𝐷𝑓/B) < 2.5, ( where is the depth of footing and B is the base
width).
( )for rectangular footing =

3. • (𝑁𝑐) for circular and rectangular footing
• For (𝐷𝑓/B) >= 2.5, (𝑁𝑐) for rectangular footing
• Ultimate bearing capacity
For
• where cu is the undrained cohesion of the soil.
