| 摘 要： | 运用基于拉格朗日原理的有限差分软件Flac^3D作为基本工具，对某隧道盾构下穿近距离既有地铁出入口施工过程进行三维数值仿真分析，计算结果表明施工过程对地层沉降有不可忽视的重要影响，必须加以考虑，得出结构所在地层在盾构推进过程中的变形规律，从而为类似工程的设计与施工采取相应的措施提供依据和支持。 |

| Abstract: | According to the nonlinear characteristics of the process of building underground project,deformation of soil mass is analyzed as a construction control objective.Based on practical engineering,a numerical model of shield tunneling is built to sim- ulate the influence of the footpath of metro-station.Space-time effect aroused shield tunneling is studied in detail by Flac3D in this paper.The results indicate that the effect induced by construction cannot be ignored.Some characteristics of deformation of soil... |
