The invention relates to the field of floating amount measuring devices, in particular to a shield tunnel segment floating simulating device and a using method.The shield tunnel segment floating simulating device comprises a model box used for containing soil, a simulating shield tunneling machine is arranged in the model box and comprises a shell, a plurality of segments are arranged in the shell, the segments are mutually spliced to form a long cylinder, and the long cylinder is arranged in the shell. A power device is arranged outside the model box and used for pulling the shell to move in the axis direction of the duct pieces, floating detection devices are arranged on the duct pieces and used for detecting the floating amount of each duct piece, and a grouting device is arranged on the outer side of the model box and used for injecting grout between the shell and the duct pieces. At least one side face of the model box is formed by splicing transparent acrylic plates, the transparent acrylic plates are c
