Steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. Consequently, Electrochemical Impedance Spectroscopy (EIS) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect ...

Liquefaction hazard induced by seismic events might affect the stability of buried pipelines, with permanent displacements embedded structure as a consequence. In this context, pipe uplift is main concern, already widely discussed in literature. paper, further insights to assess phenomenon and related effects on pipelines are provided based results shaking table tests pipes different apparent u...

The paper examines the behaviour of buried continuous pipelines crossing strike-slip faults using experimental and numerical modelling. A newly developed experiment setup is presented along with derivation relevant scaling laws non-dimensional terms governing global response to faulting. Four model tests are carried out understand performance results through derived framework. Three-dimensional...

The behavior of buried offshore pipelines subjected to upheaval buckling has attracted much attention in recent years. Numerous researchers have made great efforts investigate the influence different soil cover depth ratios, strengths and pipe-soil interfaces on failure mechanisms bearing capacities during pipeline uplift. However, spatial variability been relatively limited. To address this ga...

The practice of deep-braced excavation in congested urban environments involves frequently buried pipelines, which can exert a significant effect on the performance excavation. objective this paper is to investigate 12.5-m-deep-braced spanned by two shallowly large-diameter pressurized pipelines. A suspension structure installed within protect situ pipelines during construction. investigated pe...
