摘　　要：随着综合管廊的大规模建设以及绿色建造技术的发展,综合管廊预制拼装技术得到广泛应用。根据大量震害实例,预制拼装综合管廊的纵向拼缝通常为其薄弱部位。本文以盐城市东进路东延地下管廊工程中的预制拼装管廊为例,运用反应位移法,对纵向拼缝的抗震性能进行了分析。发现纵向拼缝在横向地震位移作用下的变形以剪切错动为主,最大变形量能够满足设计要求。表明在低烈度的地震作用下预制拼装综合管廊具有较好的抗震性能,对于高烈度的地震需进一步研究。With massive construction of utility tunnel and development of green construction technology,prefabrication and assembly technology has been used widely.According to a large number of examples of earthquake damage,research on seismic behavior of joints should be given priority while joint of prefabricated tunnel is the weakest part usually.Utility tunnel of Yancheng Dongjin Road East Extension Project was taken for example,in which the reaction displacement method was adopt to analyze seismic behavior of longitudinal joints.Mainly shear shift of longitudinal joints was found under transverse seismic displacement,the maximum deformation could meet design requirements,which showed that prefabricated tunnel had better seismic performance under low intensity earthquake action,while high intensity earthquake action required further study.
