摘　　要：为探讨干式连接分片预制装配式综合管廊的地震响应,以某大空间综合管廊实际工程为例,基于有限元分析法采用商业软件ABAQUS建立土体-综合管廊的三维数值模型,探讨不同地震波作用等对管廊结构的地震响应和影响规律。结果表明综合管廊角部为整体结构的最薄弱环节,在抗震设计中应予以重视;在多遇地震、设防地震条件下,管廊加速度响应随结构埋深的减小而增大,但在罕遇地震工况下却恰好相反,其中EI Centro地震动对结构的地震响应较为明显;管廊顶、底板间的相对位移与地震动参数几乎无关联,经计算其对应的剪切角满足我国规范要求。In order to investigate the seismic response of the dry-connected split-prefabricated utility tunnel,a practical project of a utility tunnel with large space was taken as an example.Based on the finite element analysis method,a three-dimensional numerical model of soil-utility tunnel was established by using commercial software ABAQUS.The purpose was to discuss the seismic response and influence mechanism under various seismic waves chosen.The results showed that the corner of the utility tunnel was the weakest areas of the whole structure,which should be paid more attention to,especially during the seismic design.When the frequently occurred earthquake and the fortification earthquake occur,the acceleration response of the utility tunnel increased with the decreasing buried depth of the structure,but it would turn to be the opposite as the appearance of the severe earthquake.The seismic response of the structure was more obvious under the action of El Centro ground motion.The relative displacement between the top and the bottom was almost not related to the ground motion parameters,and the corresponding shear angle meet the requirements of the Chinese code.
