長距離パイプラインのライフタイム危険度評価について

概要

論文の詳細を見る
The reliability-based design methodology for the transmission high-pressure gas pipeline is described. Limit state design criterion is introduced for the lifetime failure assessment in the seismic environment, while the maintenance activities including field patrols, periodic inspections and repair works are also teken into consideration. Pipe damages, which are caused by potential defect, corrosion, earthquake ground displacement, settlement and the third party sccident, are classified into three major damage modes which include tension/compression, bending and dent with gouge. The assessment is made for the transmission pipeline system which is surrounded with various hazards spatially distributed along the pipeline route.
