When the pipeline is in a rugged topography along the line, geological disasters such as landslide, debris flow and settlement are easily formed, soil around the pipeline is likely to be displaced and act on the buried pipeline due to the geological disasters, the pipeline is slightly deformed under the action of soil load, so that local stress concentration is generated on the pipeline, and after comprehensive stress borne by the pipeline exceeds allowable stress, the pipeline is likely to break, bend and other accidents. The geological disasters such as landslide have a long development period which is divided into an initial stage, a stable stage and an acceleration stage. The initial stage and the stationary stage are long in duration and have small displacements, and generally have no influence on the pipeline. Potential geological disaster points can be found out by methods such as geological survey along the line, periodic line patrol and the like in the initial stage and the stable stage. Once entering the acceleration phase, the geological disaster body will generate larger deformation in a shorter time and generate larger load to the pipeline. In order to ensure the normal operation of the pipeline, corresponding maintenance and monitoring measures need to be implemented before the geological disaster enters the acceleration stage, so as to eliminate the influence of the geological disaster on the pipeline.
At present, the means for carrying out nondestructive detection on the pipeline are mature, including magnetic flux leakage detection, eddy current detection, weak magnetic detection and the like, but the means can only detect the safety state and stress characteristics of the pipeline at a certain moment, but cannot reflect the stress change of the pipeline at any moment.
