A one- parameter family of totally anisotropic Bianchi type-II string cosmological models with bulk
viscous fluid in Lyra geometry is investigated. Exact solutions of Einstein field equations have been
obtained by constraining the the constant deceleration parameter which yields power-law form of
the average scale factor. Some physical and geometrical properties of the models along with the
physical acceptability have been also discussed.
