Failure prediction of buried pipe network with multiple failure modes and spatial randomness of corrosion

Buried pipes, as a significant civil infrastructure, play a vital role in water, oil and gas transports. In this paper, a systematic method is developed to accurately predict the failure probability of a buried pipeline network at various levels of failure mode, pipe segment and whole pipeline system. A framework of system reliability is proposed to integrate the ultimate and serviceability failures. The random field theory is employed to model...
