Following the half-space theory of dynamic foundation, the basic vertical motion equations of basic mass static spring stiffness fixed resonance damping form are deduced based on rigid pressure distribution, flexible pressure distribution and parabolic pressure distribution. It is also pointed out that the basic pressure distribution affects the basic dynamic response Significant impact, can not be ignored. Then the problem of the value of the foundation damping parameters and the practical calculation method of dynamic response are discussed. At the same time, based on the analysis of several measurement methods of foundation dynamic parameters, the relationship between model test method and half-space theory is demonstrated, and some problems existing in the measurement method of foundation dynamic parameters are discussed
