摘要
在讨论浅埋暗挖地铁隧道开挖所引起的应力和位移释放的基础上,进行了隧道开挖卸荷的有限元模拟计算,讨论了开挖方式对地层位移释放的影响。模拟结果可指导隧道的施工设计。
Based on basic concepts of stress relief and displacement relief in tunnel excavation process, a FEM simulation calculation for unloading under tunnel excavation is carried out. The effects of tunnel excavation modes on the displacement relief of strata are discussed. The calculation results may be used as a reference for selecting tunnel construction methods.
