Superposition of photon subtraction and addition n times excited chaotic field was constructed. Using numerical methods, the squeezing, antibunching effect and statistical property of the quantum state were analyzed. The influences of the average photon number of chaotic field, superposition coefficient of operators and times of operators operation on its quantum properties were discussed. Numerical results show that the squeezing is not displayed, while the antibunching effect and sub-poissonian statistical property are displayed. Further, its antibunching effect and sub-poissonian statistical property are weakened with increase of average photon number of chaotic field. Its antibunching effect and sub-poissonian statistical property are strengthened as the ratio of photon operator addition in superposition operation increases. On the other hand, its sub-poissonian distribution property is strengthened with increase of times of operators operation.
