As one of the typical geological hazard, landslide seriously threatens the safe operation of buried pipelines. If the limit landslide displacement that the pipeline can bear can be accurately predicted, the pipeline failure accident can be effectively predicted combined with advanced landslide monitoring technology. In view of this, firstly, a pipe-soil interaction model with nonlinear contact was established and verified. Then, the effects of model parameters and boundary conditions on simulation results were discussed. Finally, the prediction method of the limit landslide displacement for stress/ strain criterion is researched. The conclusions are as follows. The nonlinear contact pipe-soil interaction model with infinite boundaries on both sides is more suitable for the mechanical response analysis of pipeline under real landslide conditions. Using this model, the large deformation and separation of pipeline and soil can be effective simulated by that model, the limit landslide displacement based on stress and strain criteria can also be predicted. This paper provides an effective technical means for the safety design of pipelines in mountainous areas and the prevention and control of landslide accidents. [ABSTRACT FROM AUTHOR]
