[0040] By monitoring the internal stress and deformation of the rock-concrete structure, the load-bearing and deformation of geotechnical engineering can be monitored, so as to make an accurate evaluation of its stability. Based on this, this embodiment provides a rock-concrete structure stability monitoring and early warning method based on static magnetic field detection with good immediacy, strong adaptability and high reliability to solve the existing rock-concrete structure stability monitoring and early warning method The method cannot reflect the internal changes of the rock-concrete structure and the technical problems of insufficient reliability of the monitoring results. The method is suitable for the monitoring and stability evaluation of the load-bearing and deformation conditions of geotechnical engineering. The execution flow of this method is as follows figure 1 shown, including the following steps:
[0041] S101, prepare magnetic concrete specimens with concre...
