摘　　要：在市政工程中,超浅层顶管作为一种非开挖的施工技术,具有保护环境和不中断交通、不影响居民的正常生活等优点。通过有限元模拟超浅层顶管穿越路基时引起路基地层的变化情况,得出了超浅层顶管施工对浅埋覆盖路基土层移动的影响范围。As a trenchless technology of municipal engineering,pipe-jacking tunnel technique has much advantages such as not disturbing the traffic and dwellers and protecting the environment of city.By using FEM, the movement and deformation of stratum which are aroused by extra-shallow-underground-pipe jacking tunnel construction are analyzed in this paper, and then the impact area in extra-shallow-underground-pipe jacking tunnel construction is calculated.
