In this paper, we study the Cauchy problem of generalized Boussinesq equation with combined power-type nonlinearities utt - uxx + uxxxx + f(u)xx = 0, where f(u) = ∑lk=1 ak|u|pk-1u or ∑lk=1 ak|u|pk-1u - ∑mj=1bj|u|qj-1u. The arguments powered by potential well method combined with some other analysis skills allow us to give the sharp conditions of global well-posedness. And we also characterize the blow-up phenomenon.
