摘要
介绍了有限差分数值计算软件FLAC(fast lagrangian analysis of continua),采用FLAC对地下圆形市政隧道进行二维数值模拟,分别进行了隧道自重应力场的模拟计算、隧道开挖模拟计算和隧洞支护后模拟计算.得出了隧道位移、变形、各种应力云图等重要工程信息,其结论可为工程施工提供依据,以便更加安全、经济、合理地完成工程建设.
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.
