Safety Monitoring of Buried Pipeline Subjected to External Interference Using Wireless Inclinometers

Failures occurring in buried pipelines are usually associated with structural damage externally induced by surface loading or permanent ground deformation. In the framework of structural health monitoring (SHM), this paper presents a real-time technique for safety evaluation of continuously welded underground pipelines subject to external interference by using quasi-distributed wireless inclinometers. Based on the multiple inclination measurements, a fitting model combined with indirect adjustment theory and the general solution of the differential equation of beam model on elastic foundation are developed to reconstruct the inclination equation. The deflection curve is then derived to locate the abnormal surface loading and permanent ground deformation. Stress is also calculated to evaluate the performance of the buried pipeline. The error propagation from inclination measurement to the calculated stress is investigated as well. Numerical studies verify the fitting model proposed in this paper, which is of great precision to fit the rotation equation as well as calculate the deflection and strain.
