A tunneling method of a slurry shield passing through an anchor cable zone in a long distance comprises the following steps that 1, reinforcing is conducted on soil masses within the range of 5 m-6 mon the two sides of the central line of a to-be-excavated tunnel; 2, drilling and anchor distributing are conducted on the reinforcing areas; 3, a manual gate valve is mounted between a quarrying boxof a shield mechanism and a slurry discharging gate valve of a soil bin; 4, the quarrying box of the shield mechanism is transformed; 5, a slurry parameter used by the shield mechanism is set; and 6,a shield tunneling parameter is set, till excavation of a designed shield route is completed, and construction is ended. The tunneling method solves the technical problems that a slurry discharging pipe and the quarrying box are clamped deadly or blocked by an anchor cable, a cutter disc is wound, the aperture ratio of the cutter disc is decreased, and a cutter tool is damaged in the long distanceanchor cable zone passing through construction process of a traditional slurry shield.
