  We propose the universal approach to describe spreading widths of monopole,
dipole and quadrupole giant resonances in heavy and superheavy spherical
nuclei. Our approach is based on the ideas of the random matrix distribution of
the coupling between one-phonon and two-phonon states generated in the random
phase approximation. We use the Skyrme interaction SLy4 as our model
Hamiltonian to create a single-particle spectrum and to analyze excited states
of the doubly magic nuclei $^{132}$Sn, $^{208}$Pb and $^{310}$126. Our results
demonstrate that the universal approach enables to describe gross structure of
the spreading widths of the considered giant resonances.
