摘要
文章从隧道开挖和支护的安全性角度出发,论述了浅埋偏压隧道洞口设计与施工措施,并采用了三维快速拉格朗日差分法(FLAC3D)对在施工过程中的支护数据进行模拟,通过对开挖支护后围岩的应力场、位移场以及塑性区特征的分析针对性提出一些建设性建议,以期对施工有所帮助。
Articles from a security point of tunnel excavation and shoring, discusses the shallow, partial tunnel portal design and construction measures, and the use of three-dimensional fast Lagrangian method（FLAC3D） on the construction process of supporting data simulation, to make some constructive suggestions by the stress field, displacement field and plastic zone features rock excavation and support after the analysis targeted to help the construction.
