A plurality of multifunctional underwater 3D displacement meters are arranged in a lattice and connected sequentially; four rotation shafts may be rotatably mounted in a housing and extend in a vertical direction, one end of the rotation shaft and the housing are connected to a compressible spring, four perforations penetrate the housing in a circumferential direction at intervals, the metallic lines correspond to the perforations one to one, one end of the metallic line is wound around the rotation shaft, and the other end thereof penetrates out of the perforation and is connected to the metallic line of the adjacent 3D displacement meter; and the displacement meter corresponds to the metallic line for measuring a take-up and pay-off length of the metallic line, and a three-axis acceleration sensor and a fluxgate monitor inclination angle change and azimuth angle change of the 3D displacement meter.

The present disclosure relates to a device for laying out a prefabricated magnetic field and a method for responding state of a slip mass in the prefabricated magnetic field. The device may include a traction mechanism, a control mechanism and a layout probe. The layout probe may include a shell, a circuit board and at least one set of layout mechanism equipped in the shell. The layout mechanism may include a cartridge, a screw pole, an electromagnet, a driving mechanism and a pressing mechanism. The traction mechanism may lay down the layout probe to a default location of a drill hole. The control mechanism may control the driving mechanism to transmit an uppermost permanent-magnet in the layout probe to the cartridge nozzle and be attracted by the electromagnet. The pressing mechanism may move the electromagnet which presses the permanent-magnet in the inner wall of the drill hole.
