Variants of Inertial Forces at Nonlinear Subsoil Vibration.

The Green function is derived and is taken as a dynamic influence function of deflection for stationary time behavior. For solution of the integral equation the iterative method is used starting with the first approximation given by linear deflection. Nonlinear deflection of subsoil in the first approximation is given by one equation for the second variant and by another equation for the third variant of inertial forces formulation. The relative simplicity of analyzed subsoil model provides solutions of dynamic problems, which bear fundamental signs of real subsoil action. Advantages of the model are even more apparent when problems of interaction of subsoil with construction are concerned.
