Abstract

Landslides are one of the primary dangers associated with gas pipelines. Pipeline spans can be divided into two categories: longitudinally traversing and laterally traversing. The load brought on by a landslide can cause pipeline failure, thus stress analysis of both ways of traversing is of great necessity. Through stress analysis, the junction of the conventional buried pipeline and the landslide has been confirmed as coming under the heaviest loads. Therefore, stress checks against accidental loads should be emphasized during the stress analysis of gas pipelines traversing sliding masses.

Keywords: Gas pipeline, landslide, lateral traverse, longitudinal traverse, pipeline crossing, slide mass, stress analysis.
