| 摘 要： | 以上海市轨道交通明珠线二期工程浦东南路站-南浦大桥站区间近距离叠交隧道盾构施工为研究对象,采用三维非线性有限元,对近距离叠交情况下后建隧道盾构施工引起老隧道衬砌的应力和变形进行了模拟,并研究了土层性质、隧道覆土厚度、隧道间相对位置、隧道间相对距离等因素与隧道间影响的关系。结果表明,隧道间相对位置、相对距离对隧道间相互作用的影响非常大,应引起足够的重视。

| Abstract: | This paper presents the numerical simulation of the tunnel project in Pearl Line of Shanghai Metro from South Pudong Station to Nanpu Bridge Station using a 3D nonlinear finite element method. The influence of new tunnel on old tunnel during shield tunneling is studied. Some influential factors affected on the interaction of parallel tunnels are also evaluated. The results show that the relative position and net distance between the runnels have great influence on the interaction. |
