A building is proposed in an area having thick deposit of silty clay. The water table is at the ground surface. The saturated unit weight of soil is 18 kN/m3 and unit weight of water is 10 kN/m3. The maximum vertical load (P) on a column of the proposed building is 2000 kN.
Consider σz ≤ 0.1 σ′v for computation of the minimum depth of soil exploration.
σ′v is the effective vertical overburden stress. σz is the increase in the vertical stress at depth z below load P as per the Boussinesq's stress theory.
Based on above, the minimum depth (in m) of soil exploration required for the foundation design is ________ (rounded off to two decimal places).
