| 摘 要： | 以深圳地铁3号线红岭中路站~东门中路站两个盾构区间小净距空间重叠隧道段为背景,采用有限元数值模拟研究手段,对小净距空间重叠隧道运营过程中上洞列车通过时,上、下两洞结构的力学行为进行数值模拟研究,得出了由于上洞列车振动引起下洞各点附加加速度变化的最大值位于下洞拱顶内侧以及引起地层附加位移较大区域的分布范围等结论,直接指导设计。

| Abstract: | on the basis of overlapping sectional shield tunnel with small clear distance between Honglingzhonglu Station and Dongmenzhonglu Station of Shenzhen Metro Line 3,in the paper the numerical simulation study has been made on structural mechanical behavior of up-down tunnel when the train passes through the up-tunnel during the operation of overlapping tunnel with small clear distance with FEM.Conclusion has been drawn to directly guide the design and references for other homogeneous engineerings have been provided. |
