We extend the deformed relativistic Hartree-Bogoliubov theory in continuum(DRHBc)to go beyond-mean-field framework by performing a two-dimensional collective Hamiltonian.The influences of dynamical correl-ations on the ground-state properties are examined in different mass regions,picking Se,Nd,and Th isotopic chains as representatives.It is found that the dynamical correlation energies(DCEs)and the rotational correction energies Erot in the cranking approximation have an almost equivalent effect on the description of binding energies for most deformed nuclei,and the DCEs can provide a significant improvement for the(near)spherical nuclei close to the neutron shells and thus reduce the rms deviations of S2n by ≈ 17％.Furthermore,it is found that the DCEs are quite sensitive to the pairing correlations;taking 148Nd as an example,a 10％enhancement of pairing strength can raise the DCE by ≈37％.
