| 摘 要： | 地铁附近的基坑施工是影响区间隧道及地铁车站正常运营的一个重要性因素.若施工方案不当或保护措施不够,很可能引起区间隧道发生过大的不均匀变形.针对基坑开挖对地铁区间隧道的影响评价,本文提出了一种数值方法与解析方法相结合的新方式.首先利用纵向刚度等效和横向刚度等效原则建立了模拟区间盾构隧道的三维等效连续化模型,实现较为精确且...

| Abstract: | Excavation near the subway is an important factor that affects normal operations of subway station and tunnels.If either the construction plan or protection measures are inappropriate,too much non-uniform deformation may occur.According to impact assessment of excavation near subway tunnel,a new method that combines numerical method with analytic method is proposed in this paper.First,a 3D equivalent continuum model which simulates the shield tunnel is established depending on the longitudinal stiffness equ... |
