摘要：

Considering the influence of pipeline buried depth on the subgrade reaction modulus, the Winkler foundation model was modified. By using the two-stage analysis method,the displacement transfer matrix between strata and pipeline was established by using Fourier transform and the mechanical relationship between the formation settlement and the pipeline deformation was derived. Finally, a pipeline displacement prediction formula based on formation settlement was proposed. Compared with the direct analysis, finite difference method and numerical simulation, the transfer matrix method revealed the transfer relationship between pipeline displacement and stratum displacement was revealed more clearly and simplified the processes of calculating the displacement of adjacent buried pipeline. The validation of the proposed method was demonstrated through comparison with a case study and a centrifuge test. Based on the analysis on the related parameters affecting pipeline displacement, the formula for predicting the maximum displacement of buried pipelines considering various factors was established. © 2019, Department of Journal of the China Railway Society.
