Based on the layered elastic foundation soil, a reasonable mechanical model is established. Through the dynamic analysis, the vertical self-vibration characteristics of soil in layered elastic foundation and the analysis of forced reaction under vertical earthquake and explosion and impact load are given The analytical formulas in the paper and the paper provide a new analytical method for the vertical dynamic response of soils in stratified elastic foundation.
