| Abstract: | The finite difference numerical simulation software FI.AC （Fast Lagrangian Analysis of Continua） was simply introduced; the study of two-dimensional numerical simulation of the underground circular municipal tunnel was carried by numerical simulation program FLAC3D. The result of numerical simulation calculation of tunnel gravity stress field, tunnel excavation and tunnel support were separately gained. Much important information were obtained, such as tunnel displacement and deformation, all kinds of stress nephograms, which can provide foundation for the project construction, and make the project be finished more safely, economically and rationally. |
