This study is intended to analyze the stress distribution of gas pipe buried in soft ground. A numerical analysis was carried out with API 5L X 65 steel gas pipe. The analytical model describes the typical cohesive sediment bed in domestic southwest coast, and embankment load is adopted for this research. Compared with residual soil conditions, the effective stress increases by 23∼26%. From the results, it can be suggested that the difference in soil stiffness would significantly affect the stress distribution of gas pipe buried in soft clay.
