The invention provides a tunnel engineering shield tunneling machine with a self-adjusting function, and relates to the field of shield tunneling machines. A cutting tool set for cutting and drillinga tunnel, a radial force adjusting mechanism for fine adjustment of radial force generated to equipment from the tunnel and a shield body for temporary supporting of the tunnel and pavement of the tunnel face are included. The cutting tool set is arranged at the front end of the shield tunneling machine. The shield body is arranged on the rear side of the cutting tool set. According to the tunnelengineering shield tunneling machine with the self-adjusting function, according to the radial force problem existing in an existing shield tunneling machine, a special adjusting structure is designed, adaptive fine adjustment is conveniently conducted on radial force exerted on the shield tunneling machine, and the problems that when a common shield tunneling machine is used, the shield tunnelingmachine can be affected by
