“…Watson and Crick [15] evaluated the uplifted soil-pipe interactions in granular soils using a two-dimensional fnite element (FE) continuum model to derive hyperbolic and bilinear models of vertical upward forces and displacements. Kianian and Shiri [16] studied the infuence of lateral pipe-backfll-trench interaction on soil failure mechanism and lateral soil resistance under shallow and deep buried conditions, and the results can improve the prediction of the lateral response of buried pipelines in the near future. Kim and Yoo [17] determined the optimal combination of parameters for imperfect trench mounting methods based on modern fnite element analysis of deep buried concrete box culverts.…”

In order to solve the problem of differential settlement of pavement after the backfilling of urban underground comprehensive pipe corridors based on a pipe gallery project in Xiong’an New Area, the mechanical calculation model of the pipe gallery foundation pit backfilling process was simulated by ABAQUS, and the pavement settlement and the change of the pipe gallery model under different construction conditions were simulated and verified. The results show that many external environmental factors have an impact on pavement settlement, and methods such as increasing the compaction degree of backfill soil and the slope of the foundation pit, reducing the width of the pit floor, and controlling the vehicle load after work can avoid the pavement damage caused by uneven settlement.
