Varying currents, superimposed on the normal cathodic protection have been observed for many years in pipelines. These telluric currents are generally associated with variations in the earth’s magnetic field and present a continuing problem in establishing and monitoring cathodic protection systems. This problem is enhanced when magnetic storms occur. In a previous paper, a method to calculate ...

investigating the parameters influencing the behavior of buried pipelines under dynamic loading is of great importance. in this study the soil structure interaction of the pipelines with the surrounding soil was addressed using shaking table tests. wave propagation along the soil layers was also included in the study. the semi infinite nature of the field was simulated using a laminar shear box...

Modern countries utilise buried pipelines for the long-distance transportation of water, oil, and gas due to their efficiency continuity delivery receiving locations. Due soil movements such as landslides, excessive earth pressure imposed on causes damage and, consequently, leaking liquids, gases or other harmful effluents into soil, groundwater, atmosphere. By using a large-scale physical mode...

This study conducted ten freeze-thaw cyclic tests to clarify the effect of cycles on forces acting buried oil pipeline. The stress evolution in Q345 steel pipeline versus number was obtained. test results were consistent with COMSOL simulation different moisture contents bottom stress. Besides proposed XGBoost model, eleven machine-learning prediction models also applied 10–20 cycling tests. sh...

Underground pipelines are widely applied in the so-called lifeline engineerings. It shows according to seismic surveys that the damage from soil liquefaction to underground pipelines was the most serious, whose failures were mainly in the form of pipeline uplifting. In the present study, dynamic centrifuge model tests were conducted to study the uplifting behaviors of shallow-buried pipeline su...
