A parametric study was carried out to mvesttgate the sigmficance of soil layering on the vertical wbrahon of orcular machine foundations The soil deposit was ideahzed by a twolayered system m which the bottom layer was treated as a halfspace The effects ofsod layering on wave attenuation were also examined A simple analytic model was then developed to approximate the behavlour of vertical response of machine foundations on layered sod deposits. To evaluate the method, a machine foundation was analysed by the slmphfied model The results compared favourably with those from a more expensive dynamic fimte element method

An m-sltu method, the "phase method', to determine the coupled vibration parameters of foundations subjected to shdmg and rocking wbratlon is described.
