  The Heavy Shell Model (HSM) (Y. Sun and C.-L. Wu, Phys. Rev. C 68, 024315
(2003)) was proposed to take the advantages of two existing models, the
projected shell model (PSM) and the Fermion Dynamical Symmetry Model (FDSM). To
construct HSM, one extends the PSM by adding collective D-pairs into the
intrinsic basis. The HSM is expected to describe simultaneously low-lying
collective and quasi-particle excitations in deformed nuclei, and still keeps
the model space tractable even for the heaviest systems. As the first numerical
realization of the HSM, we study systematically the band structures for some
deformed actinide nuclei, with a model space including up to 4-quasiparticle
and 1-D-pair configurations. The calculated energy levels for the ground- state
bands, the collective bands such as {\beta} - and {\gamma} -bands, and some
quasiparticle bands agree well with known experimental data. Some low-lying
quasiparticle bands are predicted, awaiting experimental confirmation.
