The generalized aerodynamic force required in analysis is calculated by using horse shoe vortex— vibrational pressure doublet grid method, based on theory of subsonic unsteady lifting plane.
The results also showed that the relationship between the normalized pore water pressure and the generalized strain fit the bilinear model.

Based on the results of the earth pressure computation, the author puts forward a generalized computing equation and this equation was tested against Rankine method and coulomb method respectively.
