SUMMARY

The discussion centers on the calculation of pressure before the construction of a foundation, specifically questioning the formula used: (2.5)(16.5) + (0.5)(17.5-9.81) + (1.25)(16-9.81). Participants debate why pressure is only considered for half of the clay layer, with one user suggesting an alternative formula: (2.5)(16.5) + (0.5)(17.5-9.81) + (2.5)(16-9.81). The consensus indicates a need for clarity on the principles of consolidation pressure in geotechnical engineering.

PREREQUISITES
  • Understanding of consolidation pressure in geotechnical engineering

Homework Statement


I don't understand why the pressure before the construction of foundation is given by (2.5)(16.5) + (0.5)(17.5-9.81) +(1.25)(16-9.81) only ?. Why the pressure is taken only to the half of the layer of clay only ?

Homework Equations

The Attempt at a Solution


I think it's wrong , it should be (2.5)(16.5) + (0.5)(17.5-9.81) +[/B](2.5)(16-9.81) ..Correct me if I am wrong
