An earth layer with its cross section of 36 m long and 12 m deep is shown as the following graph. A uniformly distributed load of 1.0 e+3 N/m is applied at its upper-right corner of the width of 3 m. The elastic modulus of the earth layer is 4.0 Mpa, and its Poisson ratio is 0.25, its permeability rate is 8.64 e -4 m³/d, its viscosity is 0.3 and the fluid density is 1.0 e+3 Kg/m³.

                     

The deformation of the earth layer under the loading condition and the distribution of the permeated flow pressure are solved by the control equation of generalized Biot theory:
