8.3.2 Theory of Elasticity
There are several different methods that can be used to estimate the immediate settlement (si). One
approach is to use the modulus of elasticity E of the soil from consolidated undrained triaxial compression
tests with pore water pressure measurements (ASTM D 4767-02, 2004) in order to estimate
the immediate settlement based on the theory of elasticity. Because the modulus of elasticity is
obtained from an undrained triaxial test, it is often referred to as the undrained modulus and designated
Eu. The equation is the same as Eq. 7.9, or:
