Study on Influencing Factors of Tunnel in Seismic Performance of Adjacent Underground Pipeline

Abstract:

The existing tunnels may have an influence on seismic performance of adjacent underground pipelines. However, most of previous relevant studies are separately focused on seismic performance of the pipeline or the tunnel. In this paper, the major influencing factors of the existing tunnel in the seismic performance of adjacent underground pipelines, including joint types of the pipeline, the different angles and the distances between the pipeline and tunnel, were discussed. Numerical results show that flexible joint is the important factor which is helpful to decrease the settlement difference and the axial stress of the pipeline. Meanwhile, the relative position between the pipeline and the tunnel may also have a significant influence on seismic performance of pipelines.
