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.
