The bearing capacity equation

What this module covers

• State the three-term bearing capacity equation and say what each term represents physically
• Compute N_c, N_q and N_γ, and know which of them is derived and which is fitted
• Explain why published N_γ values differ between authorities, and what to do about it
• Identify which term dominates in clay and which in sand
