Buried concrete structure monitoring device and method

The invention discloses a buried concrete structure monitoring device and method. The buried concrete structure monitoring device comprises a base plate and a wire conduit which penetrates through the middle of the base plate and is arranged in a hollow mode. The strain resistance wire is fixedly arranged on the upper surface of the substrate in an attached mode, and the two ends of the strain resistance wire penetrate through the pipe wall of the wire pipe and penetrate out of the upper end of the wire pipe to be electrically connected with the detection mechanism; the exciting coil is sleeved on the to-be-detected reinforcing steel bar, and two ends of the exciting coil upwards penetrate out along the side wall of the reinforcing steel bar and are electrically connected with the detection mechanism; the induction coil is fixedly arranged in the wire conduit and is flush with the exciting coil in height, and the two ends of the induction coil penetrate through the wall of the wire conduit and penetrate out o
