| description | Ground deformation, which is a common consequence of surface loads, construction activities, subterranean cavitations, soil subsidence, and so on, poses a serious threat on buried pipelines in the vicinity. Aiming at the influence of ground deformation on continuously welded underground pipelines, this article presents a real-time technique for pipeline health monitoring using wireless micro-electro-mechanical system inclinometers. Based on the multi-point inclination measurements, a strategy is proposed to achieve the two-level target: (1) detection and localization of the abnormal event and (2) estimation of pipeline flexural deflection in virtue of the elastic foundation beam model and cubic spline interpolation. Numerical studies are carried out to investigate the applicable conditions of the strategy and the influence of sensor placement and measurement error on the estimation accuracy. Field testing is finally conducted on a 24-m buried steel pipeline to validate the effectiveness of the proposed method for safety monitoring of the pipeline subjected to ground deformation. |
