We systematically investigate the stability of the doubly heavy tetraquark states [QQ][qq] (Q=c and b, q=u, d and s) within the framework of the color flux-tube model involving a multibody confinement potential, σ-exchange, one-gluon-exchange and one-Goldstone-boson-exchange interactions. Our numerical analysis indicates that the states [bb][ud] with 01+ and [bb][us] with (1)/(2)1+ are the most promising stable states against strong interactions. The states [cc][ud] with 01+, [bc][ud] with 00+, 01+, and 12+, and [bb][ud] with 01- and 12+ as stable states are also predicted in the color flux-tube model. The dynamical mechanism producing those stable doubly heavy tetraquark states are discussed in the color flux-tube model.
