Abstract:
Aviation fuel pipeline is one of the important lifelines of aviation coal supply at airports. When crossing a densely populated area, the aviation oil pipeline will inevitably be disturbed by natural and human factors, such as unreasonable soil accumulation near the pipeline, when the soil load is too large, the weak foundation soil will produce different degrees of deformation, the pipeline is subjected to various complex force forms under the action of soil displacement, resulting in a series of damage to the pipeline, and eventually cause pipeline safety accidents, resulting in the loss of people’s lives and property and environmental damage. Therefore, studying the force characteristics and safety prevention and control countermeasures of buried aviation oil pipelines under the surrounding soil pile occupation pressure has a very important guiding role and practical value for ensuring the operation safety of the airport lifeline. In this paper, the stress and deformation of buried oil and gas pipelines under the action of surrounding soil piles are analyzed, the influencing factors of buried oil and gas pipeline stress under the action of soil accumulation are analyzed by finite element software ABAQUS, the detailed stress analysis of the pipeline is carried out,and the finite element simulation method is verified by on-site large-scale stacking tests.
