Abstract. We present a cylindrically symmetric solution to the dilaton-axion gravity equations. The found solution is (quasi)regular on the axis of symmetry, asymptotically flat and free from curvature singularities. From a physical point of view the solution describes a nonrotating cosmic string interacting with gravitational and dilaton-axion waves.
