Zusammenfassung: | The utility model discloses a simulation test device for simulating excavation construction of multiple shield tunnels. Box body, a plurality of horizontally-arranged hydraulic cylinders and a plurality of bearing cylinders are arranged outside the box body, a plurality of inner supporting cylinders are arranged in the box body, the hydraulic cylinders, the inner supporting cylinders and the 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, penetrate through a front end plate of the box body and are inserted into the bearing cylinders, and driven by the hydraulic cylinders. And an observation window is arranged on the bearing cylinder. According to the utility model, the segment lining of the shield tunnel is simulated by adopting the inner supporting cylinder; a gap outside the segmental lining in the actual construction process is simulated by adopting the |
