The invention discloses a supporting frame for duct pieces of a soil-disturbance-resistant split type shield tunnel. By the supporting frame, the problem that duct pieces of a formed shield tunnel deform easily when soil disturbance occurs above the shield tunnel is solved. Duct pieces (2) are arranged on a shield surrounding rock hole side wall (1); a shield trolley right sleeper (4) and a shield trolley left sleeper (16) are respectively arranged on bottom duct pieces; a right supporting frame bottom beam (7) is arranged on the shield trolley right sleeper (4) along the trend of the tunnel; right supporting frame upright columns (8) and right supporting frame longitudinal beams (9) are arranged on the right supporting frame bottom beam (7) at intervals; a right right-angled-triangle-shaped support (10) is fixedly arranged on the right side of each right supporting frame upright column (8); the structure of a left supporting frame body is the same with that of a right supporting frame body; and an upper supporting frame body is arranged on the upper portion of space between the left supporting frame body and the right supporting frame body. The supporting frame for the duct pieces of the soil-disturbance-resistant split type shield tunnel can be assembled on spot, is simple and practical and can be reused.
