In recent years, pipeline construction of shallowly buried flexible pipes is increasing. This is due to the cost of general pipeline construction with deep excavation, having depth of cover of about 1.5–2.0 times of the pipe diameter. However, buried pipeline with a shallow depth of cover has a risk of large deformation caused by traffic loads. This paper presents the behavior of buried flexible pipe with shallow depth of cover under traffic live load analyzed by D.E.M.(Distinct Element Method Analysis). As a result, it was found that the behavior of a shallowly buried pipe under traffic live load can not be evaluated by the current design according to Spangler's assumption.
