The invention discloses an indoor test device and method for simulating shield cutting of an underground diaphragm wall. The indoor test device comprises an annular pouring mold, a soil filling groove and a strain sensor. Reinforcing steel bars are erected in the pouring mold, and concrete is poured to form a diaphragm wall; the strain sensor is fixed on the reinforcing steel bar; the filling groove is used for being filled with mortar, a groove opening of the filling groove is fixedly connected with the pouring mold, and the filling groove is filled with the mortar or rock soil to simulate filling behind the wall, so that the simulation experiment is closer to the real effect. According to the indoor test method for shield cutting of the reinforced concrete diaphragm wall, the damage process of the diaphragm wall in the shield cutting process can be accurately simulated, the stress and strain data of the steel bars of the diaphragm wall can be obtained, valuable experimental data and basis are provided for s
