摘　　要：近年来我国地下空间的建设与开发高速发展,地下综合管廊建设提高了城市地下空间利用率,提升了市容市貌和美化了环境。但建设中也出现了诸多的问题,目前设计规范尚不完善,难以有效指导施工。本文以某地下综合管廊为例,构建了标准段主体结构的有限元模型,对整体结构进行了各种荷载组合作用下的受力性能分析,检算各结构受力和变形、混凝土裂缝、整体结构抗浮能力以及基地应力,以便于更好地指导地下综合管廊后续施工,同时也希望对地下综合管廊设计规范的完善起到了借鉴意义。In recent years,the construction and development of underground space in our country have developed rapidly.The construction of underground integrated pipeline corridor has improved the utilization rate of urban underground space,enhanced the city appearance and beautified the environment.But there are also many problems in the construction,the current design code is not perfect,it is difficult to guide the construction effectively.Taking an underground integrated pipe corridor as an example,this paper constructs a finite element model of the main structure of the standard section,analyzes the mechanical performance of the overall structure under various load combinations,and checks the stress and deformation of each structure,concrete cracks,the overall structure's buoyancy resistance and base stress,so as to better guide the subsequent construction of the underground integrated pipe corridor.At the same time,it also hopes to play a reference to the improvement of the design specification of the underground integrated pipe corridor.
