description The invention provides a coupling loading test device for simulating shield segment jacking force and shield tail brush pressure. Comprising a fixing device for limiting the displacement of a segment test piece, a counter-force device for providing counter-force for loading, a horizontal loading device for simulating the jacking force of a shield tunneling machine, a vertical loading device for simulating the pressure of a shield tail brush, and a testing device for detecting the strain distribution of the segment test piece, the duct piece test piece is installed on the fixing device, the annular face of one side of the duct piece test piece makes contact with the horizontal limiting block, the annular face of the other side of the duct piece test piece abuts against the horizontal loading device, the annular face of the outer side of the duct piece test piece abuts against the vertical loading device, and the horizontal loading device and the vertical loading device conduct coupling loading on the duct piec
