作为城市生命线的重要组成部分，城市地下管线的安全极大影响人们的日常生产生活。为实现对城市地下管线的精准维护，迫切需要研究交通荷载作用下管土相互作用规律。通过建立荷载-土层-管线三维数值模型，综合考虑载荷类型、土体种类、管道材质与管道埋深等因素，分析管土相互作用规律，并定量评价各因素影响程度。结果表明：浅埋条件下动荷载对埋地管道及土体的变形特征影响显著，路面结构及管道埋深提高了管道及土体的承载变形能力；相较于无管道情况，埋地管道的存在增强了土体抵抗变形能力；通过开展多元线性分析，获取了各因素的敏感性程度。研究成果可为城市管道的设计、埋设及维护提供指导依据。

As an important part of the urban infrastructure, the safety of urban underground pipelines greatly affects people's daily production and lives. To achieve accurate maintenance of urban underground pipelines, it is urgent to study the pipe-soil interaction under traffic load. A three-dimensional numerical model of the load-pipe-soil system was established, the behavior of pipe-soil interaction was analyzed and the degree of influence of each factor quantitatively was evaluated by comprehensively considering the type of load, type of soil, material of the pipeline, and depth of pipe burial. The pipe-soil interaction was analyzed, and the influence of each factor was quantitatively evaluated. The survey results indicate that dynamic load has a significant effect on the deformation characteristics of buried pipelines and soil under shallow burial conditions, and the pavement structure and the depth of the pipeline increase the deformation capacity of both the pipeline and the soil. The presence of the buried pipeline enhances the deformation capacity of the soil compared to the scenario without a pipeline. The sensitivity of each factor is determined through multivariate linear analysis. The research results can guide the design, burial, and maintenance of urban pipelines.
