Abstract:
In this paper, against the reactor building of a 1000MW Pressurized Water Reactor （PWR） nuclear station, the influence of the change of dynamic shear modulus of foundation soil on the floor response spectra of nuclear reactor building on a site of hard soil is investigated by considering soil-structure interaction （SSI）, and the sensitivity of the floor acceleration response spectra of the reactor building to the change of dynamic parameters of foundation soil is quantitatively analyzed, which may provide a reliable method and an important reference to evaluate the anti seismic safety of nuclear reactor buildings on similar sites of hard soil.
