Structural health monitoring of buried pipelines under static dislocation and vibration

Buried pipe lines are an efficient way of transporting of water, sewage, oil, and gas resources in all over the world. Since the buried pipe lines are exposed to many unexpected conditions, such as landslides, corrosion, fatigue, earthquakes, material flaws or even intentional damaging, so the inspection requirements lead to adoption of new method of maintenance, protection and conserving. This report aims to improve the trustworthiness, reliability, yet economical technologies for monitoring of behavior and manner of buried pipe lines during operation and assessing the risk of pipe lines failure. Distributed sensors (piezoelectric) are surface designed and embedded to investigate the deformation, and deflection due to unexpected and external loadings over the pipes. Vibration and frequency responses of a modeled pipeline integrated with piezoelectric sensors would be investigated to identify, locate, and quantify the structural performance of the pipelines. By implementing a Structural health monitoring system with pipelines, their structural integrity can be continuously monitored.
