The characteristics of the excess pore water pressure developed in a saturated cross-anisotropic elastic soil deposit immediately after the application of a load are theoretically examined. It is indicated that the excess pore water pressure is quantitatively equivalent to the increase in total vertical stress only when the elastic constants of soil skeleton have the relation of μh+μvEh/Ev=1, and to the increase in mean normal stress only when the soil skeleton satisfies the zero-dilation condition of μh+μvEh/Ev=1 and μv=0.5. Moreover, it can be found from numerical results that the excess pore water pressure is exceedingly affected by the anisotropy of Young's modulus of soil skeleton.
