The deformation of a
soil body follows the elastic behavior and the fluid movement is
governed by Darcy’s law. Pore water pressure and stress are related
through the concept of effective stress, which states that the total
stress is the sum of effective stress and the change of pore water
pressure. Due to its versatility, poroelastic theory has been applied
to many fields, such as soil mechanics, hydrogeology, civil engineering,
and seismology
