Abstract 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 the distribution of corrosion, considering...

Abstract In this paper, a method is developed to evaluate the probability of fracture failure of pressurized cast iron pipes subjected to pitting corrosion. A new model for corrosion pit depth is developed which considers the correlation between model parameters. The first passage probability method is employed to quantify the probability of fracture failure where the failure criterion is established based on fracture mechanics and the stress intensity factor is modeled as a nonstationary lognor...
