Influence of piles of structure induced by crossing tunnels

According to the influence problems of piles induced by the crossing No. 2 and No. 4 shield tunnels in the west terminal of Shanghai Hongqiao Comprehensive Transportation Hub, the two phrase analysis methods simplify analysis method and displacement controlled FEM method are used in the analysis of the influence of piles of structure induced by the crossing tunnels, single tunnel or multi-tunnels. The special design measures using the displacement controlled FEM in the analysis of multi-tunnels are put forward according to the analysis results. The in-situ monitoring results of construction stage certify the validity of the design measurements.
