Abstract:
Considering the influence of the Changchengqiao Station tunnel construction on pipelines, a three-dimensional finite element analysis model is established for the tunnel support structure-soil-underground pipeline coupling effect. The whole construction process is simulated and analyzed. Based on the numerical simulation results, deformation control standards for different pipeline materials are formulated accordingly, which are verified by on-site pipeline settlement monitoring data. The established pipeline subsidence control standards play a guiding role for the on-site construction.
