摘　　要：依据燃气管道与悬臂桩的相互作用关系,建立了燃气管道平行穿越悬臂桩支护基坑地段的安全间距计算模型,采用三维有限元计算模型对主要影响因素作了敏感性研究,提出了燃气管道与悬臂桩支护基坑开挖边界的安全间距建议值。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.
