摘　　要：研究目的:调线调坡是一项涉及多专业的综合性工作,是对地铁施工所产生的差、错、漏等误差,通过调整线路平纵断面,达到消除并满足各种设备限界要求的过程。地铁车站、区间结构是否侵限,关乎到地铁运营的安全,因此调线调坡作为侵限情况的检查和消除,已是目前地铁建设中不可缺少的环节。本文通过实际工程,对调线调坡设计流程及碰到的问题进行总结,希望对今后的地铁设计和施工给予帮助。研究结论:通过研究得出:(1)明挖结构施工精度容易控制,若有部分侵限,可通过结构处理满足要求;(2)盾构区间施工时,若姿态未得到有利控制,出现盾构侵限现象,应缓慢纠偏,之后调线调坡才有条件;(3)车站或区间结构突变处,须加密断面测量,避免遗漏限界受控点;(4)需注意轨道结构与区间最低点排水管道的关系;(5)轨道设计需综合考虑环评要求。Research purposes： Adjustments of track and gradient are the comprehensive multi - disciplinary work, and its purpose are to eliminate the gaps, the mistakes, the missing and the other errors produced in metro construction by adjustment of track plane and vertical section to make the track meeting the various boundary requirements of the devices. Whether the metro station and the interval structure invade the boundary or not is crucial to the metro. As the work to examine and eliminate the invasion of the boundary, the adjustment of track and gradient has become an indispensable work. Compared with the actual project, this paper sums up the design process of the adjustments of track and gradient and the problems encountered in it for giving a hand to metro design and construction. Research conclusions： From the research it is concluded ： （ 1 ） It is easy to control the construction precision of open cut structure. If any part of it invades the boundary, the treatment can be conducted to the structure to make it meeting the requirements. （ 2 ） During shield construction, if the shield invades the boundary due to no effective control of gesture, the slow correction should be made and after it the conditions for the adjustments of track and gradient can be realized. （ 3 ） The section measurement should be conducted tensely to the sharp change areas of the station or the interval structure to avoid missing the boundary control point. （ 4 ） The attention should be paid to the relation between the track structure and the drainage pipe in the lowest area. （ 5 ） The track design should comprehensively consider the EIA requirements.
