Shield tunnel segment connector mechanical property test device

The invention provides a shield tunnel segment connector mechanical property test device. The shield tunnel segment connector mechanical property test device comprises a reaction frame, a shield segment, a first support, a second support, a first force applying part and a second force applying part, wherein the shield segment is disposed in the reaction frame and comprises a first connector face and a second connector face; the first support comprises a first abutting face and a second abutting face, the first abutting face is abutted against the reaction frame, and the second abutting face is connected to the first connector face; the second support comprises a third abutting face and a fourth abutting face, and the third abutting face is connected to the second connector face; the first force applying part is abutted against a position between the reaction frame and the shield segment and used for applying radial axial pressure to the shield segment; the second force applying part is abutted against a position between the second support and the fourth abutting face and used for applying circumferential axial pressure, with set eccentric distance, to the shield segment. By the shield tunnel segment connector mechanical property test device, tunnel connector mechanical behaviors are simulated vividly according to actual conditions to increase test data accuracy.
