| description | The invention discloses a simulation test device for simulating excavation construction of multiple shield tunnels. The device comprises a box body, a plurality of hydraulic cylinders and a pluralityof bearing cylinders are horizontally arranged outside the box body, a plurality of inner supporting cylinders are arranged in the box body, the hydraulic cylinders, the inner supporting cylinders andthe bearing cylinders are coaxially arranged in a one-to-one correspondence mode, sleeves in sliding fit with the inner supporting cylinders are arranged on the outer sides of the inner supporting cylinders, the sleeves penetrate through a front end plate of the box body and are inserted into the bearing cylinders, and the sleeves are driven by the hydraulic cylinders. An observation window is arranged in each bearing cylinder. The pipe piece lining of a shield tunnel is simulated by adopting the inner supporting cylinders; the sleeves are adopted to simulate a gap outside a pipe piece liningin the actual construction |
