Patent ID: 7966165

Claim:
A soil-water coupled analyzer comprising: a processor that: inputs data on conditions of a soil skeleton and data on external forces; 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 solid skeleton including a jerk term of a second order derivative term on a time of a velocity vector 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 the regard to any of the displacements, 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 pore water pressure field; and outputs the obtained time history responses.
