The Ou River estuary deposits deep soft silt and silt clay, the pipe-jacking tunnel departures from Qidu island, then passes underneath north levee road, viewing platform, Ou River and Ou River road, finally reaches the received well. The net distance between tunnel segment and the viewing platform piles is only 230mm. In order to analyze the negative influence of large diameter pipe-jacking tunnel traversing piles of viewing platform, the numerical model is established, and the levee road settlement value is found which matches with observed settlement very well. The dynamic analysis is also conducted by EI Centro seismic wave, and the result reveals that the max displacement occurs on the segment between the rear row piles of viewing platform, and the max displacement reaches 68.6mm in the earthquake.
