%X 为了揭示地下综合管廊回填的沉降规律，以雄安新区某综合管廊项目为实例，利用有限元软件ABAQUS，基于混凝土CDO模型，建立了地下综合管廊结构数值模型，以分析管廊结构在上方填土荷载作用下的变形特征，结论提出了“多舱室，小舱室”的设计理念，管廊结构中上下板剪应力较大，因此加强该部分的抗剪强度能有效减小管廊结构变形破坏，研究成果可为类似综合管廊项目提供一定的理论指导。<br />
In order to reveal the settlement law of underground comprehensive pipe gallery backfilling, a numerical model of underground comprehensive pipe gallery structure was established using finite element software ABAQUS and concrete CDO model, taking a comprehensive pipe gallery project in Xiong’an New Area as an example. The deformation characteristics of the pipe gallery structure under the loading of the upper filling soil were analyzed. The design concept of “multiple compartments, small compartments” was proposed, and the shear stress of the upper and lower plates in the pipe gallery structure was relatively high. Therefore, strengthening the shear strength of this part can effectively reduce the deformation and damage of the pipe gallery structure, and the research results can provide certain theoretical guidance for similar comprehensive pipe gallery projects.
