Consolidation Settlement at the center of square footing | Overconsolidated Soil

In this video, we are going to learn how to calculate the consolidation settlement at the center of square footing. We will be also learning how to calculate the stress increase at the center of footing at any specific depth.

Question: A site originally consists of a 3 m deposit of saturated clay overlying bedrock. A 1 m thick fill will be constructed and used to support a 2 m x 2 m square footing. Calculate the ultimate consolidation settlement of the clay if the footing supports a 1000 kN load. Base your calculations on the initial and final stresses at the midpoint of the clay layer ( under the center of the footing). Properties of the clay are as follows: Cc = 0.4, Cr = 0.08, σp' = 50 kPa, w = 0.40, Gs = 2.7

why do you input the initial overburden pressure as 7.8, not taking into account the pressure from the 1m of fill above the clay layer?

The original ground surface is at 1 meter below the footing (building)

Sir what is A and n and m? A is the area of the corner footing or length?

Thanks for watching Master Civil Engineering

A and B are the sides of small square footing and m and n are the unitless coefficients which are used to determine Influence Coefficient

Sir, what is 250 in stress calculation.......

[@MasterCivilEngineering]

Thanks for watching dear

[@MasterCivilEngineering]

250 kPa is the stress at the base of the footing due to load on the footing

[@esmettazlan2120]

How about circulation foundation example?

Will make an video soon on circular footing
