Optical spatial screening solitons in photorefractive crystals in a one-dimensional case based on Kukhtarev model is studied. The new numerical scheme according to the Crank-Nicholson method accompanied by the central difference method is introduced to find the bright soliton solution. Simulation of the propagation is performed to show the dynamical evolution of solitons and check their stability. Numerical investigation of the interaction between incoherent screening photorefractive solitons is also performed. The influence of intensity and initial separation of the mutually incoherent self-trapped beams are discussed in detail.
