The embodiment of the invention provides a device and method applicable to layered settlement test of tunnel surrounding rock of simulation experiment. The device comprises a resistance coil, testing points and a resistance reading instrument, wherein the testing points are arranged on the resistance coil; guide lines educed from the testing points and a guide line educed from the top end of the resistance coil are respectively connected onto the resistance reading instrument; the testing points are plastic discs, and electric brushes are fixed in the four directions of the plastic discs and are contacted with the resistance coil. Ring-shaped conductors in the plastic discs are provided with wiring terminals; one guide line is educed from one wiring terminal and is connected to the resistance reading instrument. The device and the method provided by the embodiment of the invention have the advantages that the need for indoor model test of layered settlement of the tunnel surrounding rock can be well met, the variation of the positions of the testing points can be conveniently obtained by determining the resistance of the coil at the testing points, and further the settlement values of the testing points are obtained; and the testing points are independent from each other, so that the mutual influence between magnetic rings with closer distance in the traditional testing instrument is reasonably avoided.
