The soliton propagations in lead glass separately with circle and rectangle boundaries are theoretically and experimentally investigated. Based on the image beam method the soliton propagation in lead glass is comprised of two independent processes: the soliton forming and the soliton steering as a whole. The soliton-forming process is boundary independent, which is caused by the source beam itself induced refractive index distribution. The force which leads to the soliton steering essentially comes from the boundary effect and is equal to the force between the soliton beam and all of the image beams. The numbers of the images are one and infinite respectively for the boundaries of circle and rectangle. This results in a different steering force with a different boundary. The closed-form solutions of the soliton critical power and the steering trajectories are in good agreement with the experimental results.
