摘　　要：自2012年以来,综合管廊工程建设在乌鲁木齐市得到了大力推进,规划近550 km的综合管廊,目前已建成管廊长度达数十公里。因工程特点、地质情况、边界条件的不同,新的项目在建设过程中会遇到新的问题。基于乌鲁木齐市某综合管廊工程实例,对设计过程中的相关问题进行探讨。主要提出诸如两舱管廊投料口的新做法、标准段支座处的纵筋锚固问题、下穿新建车行地道时的管廊受力问题、临近高架桥引道挡墙引起的管廊附加荷载等问题,通过分析得出相应的解决方案。Since 2012,the construction of integrated pipe gallery has been greatly developed in Urumqi,with nearly 550 km of integrated pipe gallery planned.At present,the completed pipe gallery is tens of kilometers long.Due to different engineering characteristics,geological and boundary conditions,new problems will be encountered in the building process of a now project.Based on an engineering example of an integrated pipe gallery in Urumqi,this paper discusses the related problems in the design process.Some problems are put forwarded mainly in this paper,including the new method for the feeding port of two compartment pipe gallery,the anchoring problem of longitudinal reinforcement at the support of standard section,the stress problem of pipe gallery when passing through the new vehicle underpass and the additional load of pipe gallery caused by the retaining wall near the viaduct approach.Through analysis,the corresponding solutions are obtained for reference in similar engineering design.
