Abstract. In this paper we have investigated plane symmetric string cosmological model with bulk viscosity. To get a deterministic model, it is assumed that ξ = Kθ^m, where ξ is the coefficient of bulk viscosity and θ is the scalar of expansion and a relation between metric potential B = RAⁿ. The physical and geometrical aspects of the model are also discussed.
