Anti-sliding method for crossing and pushing type landslide aviation oil pipeline based on combined pile wall

The invention discloses an anti-sliding method for a crossing and pushing type landslide aviation oil pipeline based on a combined pile wall. The anti-sliding method comprises the steps that the combined pile wall is arranged behind the crossing and pushing type landslide aviation oil pipeline; respectively designing the size parameters of the retaining wall and the anti-slide piles according to the landslide parameters and the aviation oil pipeline parameters; carrying out calculation by utilizing finite element software according to the pipe-soil-oil-anti-sliding measure multi-physics field complete coupling model, and extracting a pipeline equivalent stress cloud picture and a displacement cloud picture; according to the pipeline equivalent stress cloud atlas and the displacement cloud atlas, pipeline stress distribution and deformation conditions are analyzed; and the combined pile wall is optimized and upgraded. Segmented protection treatment is conducted on the aviation oil pipeline landslide, the retai
