We present some solutions of Bianchi type I cosmological models with bulk viscosity. Exact solutions are given when the universe is filled with stiff matter while the viscosity coefficients are constant or proportional to the energy density. Effects of the bulk viscosity are found to smooth out the anisotropy of the universe and create matter by the gravitational field in the course of evolution. At the final stage, cosmologies are driven to the infinite expansion state, the de Sitter spacetime, or the isotropic Friedmann universe.
