- Abstract:
- Large-size buried pipelines are an efficient way of transporting of water, waste water, sewage, gas, and oil resources in across the world. Since the buried pipe lines are exposed to many unexpected conditions, such as landslides, corrosion, fatigue, unexpected loading, earthquakes, material flaws or even intentional damaging, so the inspection requirements lead to adoption of new method of maintenance, protection and conserving of pipelines. This proposed project aims to improve the trustworthiness, reliable, yet economical technologies for monitoring of behavior of buried pipe lines during operation and assessing the risk of pipe lines failure. Piezoelectric sensor is bonded on the surface of the pipe to investigate the deformation, and deflection due to unexpected loadings, such as foundation cracks, destruction, and leakage. Frequency responses of a modeled pipeline integrated with piezoelectric sensor would be investigated to identify and to show the functionality and structural performance of the pipelines. The characteristics and consequence of buried pipes under various loading conditions, deflection, and pressure drop leading to failure is studied.
