• The prediction of failure lives and the estimation of remaining lives of various buried pipelines are very important to protect human-being' daily lives from unexpected accidents. The fracture mechanics approach may do a good role to reduce to check the degree of the integrity of buried pipelines by using both stress (circumferential stresses) induced by varying boundary conditions in buried pipelines are reviewed in detail. The boundary conditions include the soil pressure, the width of trench, and the vehicle loading. The effect of hoop stresses on the external circumferential crack in buried pipelines are investigated by using a simple model proposed by this study, This study may be extended to investigate axial and mixed mode loading cracks as well.
