| Abstract: | 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. |
