摘要：Disfigurements commonly occur in manufacture and buried pipeline under service. The collapse loads of span pipeline with bulk indentation near the fixed end are calculated with clastic-plastic analysis by finite element method for pressure, temperature. deadweight and wind loadings. The shape and size of defect effects on the limited loads are discussed. Invalidation of the model bor the bent pipe is analyzed.
