Claim One:
1. A soil-water coupled analyzer, comprising: a data input unit that inputs data on conditions of a soil skeleton and data on external forces; and an analysis module that performs deformation analysis of the soil skeleton, wherein the deformation analysis formulates simultaneous motion equations of rate type with respect to a pore water pressure and a velocity of the soil skeleton including a jerk term of the soil skeleton, based on the input data on the conditions of the soil skeleton and the input data on the external forces, and integrates the formulated simultaneous motion equations as needed under a given geometric boundary condition with regard to any of a displacement, a displacement rate, and an acceleration, a given dynamic boundary condition with regard to either of a stress and a stress rate, and given hydraulic boundary conditions with regard to either of the pore water pressure and a total water head and a flow of pore water, so as to obtain time history responses of a velocity field and a pore water pressure filed.
