Stress and suction in the volume change of unsaturated expansive soils

By: A. Sabbagh

Sinnappoo (Ravi) Ravindran

Thanks Mohannad

I will read it.

Best regards

Ravi

B.R. Madhusudhan

Depends on the degree of saturation. If the degree of saturation changes with depth then obviously the suction will change too.

Thanks Madhusudhan for your advice.

Much appreciated.

Binu Kumar

It varies with stress or it can named here pressure. The soil suction is a function of hydraulic conductivity, pressure and saturation.
