The q-deformed Hamiltonian with U(5) symmetry in s , d interacting boson model can be constructed by using quantum algebra SUP (2), SUq(1,1) and q-deformed boson operator. The energy spectra and E2 transition rates of 110~114Cd iso topes are calculated. The calculated results agree with the experimental data rather well. Analyses on the calculated results show that the q-deformed U(5) limit is deviated from the symmetry in the original model and the degree of deviation is dependent on the deformation parameter.
