- The inflection area of the existing tunnel is 6.5D in longitudinal direction and 3D in transversal direction. 铁路隧道纵向受影响范围为6.;5D，横向受影响范围为3D。
- The test results show that the tunnel with smaller values of C/D and of d/D will suffer the larger bending moment on the existing tunnel lining caused by jacking force. 针对潜盾施工问题，本研究分为两大主题来讨论：第一部份探讨不同深径比下单隧道盾尾间隙闭合后，地盘应力释放所造成的隧道衬砌弯矩大小与分布情况；
- Secondly, a new tunnel was drilled nearby the existing tunnel with various distance-to-diameter ratios (d/D), and the jacking force was applied on the tunnel face. 现行一般多采用潜盾工法来进行隧道开挖工作，在施工过程中，由于地盘应力变化导致周边地盘变位，亦造成地表结构物受损。
- By means of 3D-FEM, the process of undercrossing shield tunnel construction is simulated and the changing laws of displacement, deformation and internal forces of the existing tunnel are analyzed. 采用三维有限元方法对正交下穿盾构隧道施工进行模拟，分析新隧道动态掘进时既有隧道位移、变形和内力的变化规律。
- The models were conducted to figure out the changes of bending moment on the existing tunnel lining caused by the jacking force, tail voids closure and the back grouting pressure on the new tunnel. 此外，施工中的隧道亦可能与营运中的隧道擦身而过，因此如何加强既存隧道的保护以及新挖隧道施工过程的管理与规划成为相当重要的课题。
- Undercrossing tunnels are frequently constructed by the shield-driven method in metro projects.Shield tunneling affects the existing tunnel inevitably. 摘要在地铁工程中，常采用盾构法修建正交下穿隧道，新隧道的掘进不可避免地对既有隧道产生影响。
