摘　　要：为了解地下综合管廊在超重交通荷载作用下的受力变形特性,基于湖南某综合管廊实体工程,通过有限元分析软件ABAQUS进行了数值模拟,研究了二维工况下重型车辆荷载以垂直走向通过综合管廊结构时结构的受力和构件位移特征。结果表明,超重荷载对管廊结构产生较为明显的竖向位移,超重荷载对结构整体、分隔墙、综合舱顶板竖向位移有明显的影响,研究结论可为今后管廊的建设运营及维护提供参考价值。Based on the particular utility tunnel project in Hunan province,the author has researched the heavy traffic load in vertical direction go through over utility tunnel structure in 2 D condition. The research intends to explore the utility tunnel＇s bearing and deforming behavior with the finite analysis software（ABAQUS）. The result has indicated that the heavy traffic load has a relatively obvious vertical displacement to utility tunnel structure. Moreover,the heavy traffic load has a significant effect on the U2 displacement of the whole structure,the division wall and the top sheet of the integrated cabin. Though the analysis of the utility tunnel structure,it may provide useful reference value for the construction operation and maintenance of utility tunnel.
