| Abstract: | According to the relationship between gas pipeline and cantilever pipes, the calculation model of safety distance that gas pipeline horizontally passes through foundation ditch of cantilever piles is established. The research on the sensibility of the main influence factors is performed using 3D-FEM. The recommended value for safety distance between gas pipeline and excavation boundary of foundation ditch of cantilever piles is proposed. |
