| 摘 要： | 为纠正土建偏差,消除侵限,调线调坡是地铁隧道主体结构完成后,铺轨之前的一项十分必要的工作。首先要进行断面测量、建筑限界检查,然后通过调整设计线位和坡度,减小隧道侵限值,满足限界要求。以圆形隧道为例,介绍调线调坡设计的全过程,并总结调线调坡的方法和设计要点。

| Abstract: | After completion of the main tunnel structure of the metro tunnel,the fine-tuning of the line and slope is a very important job before track-laying to correct structure deviations and eliminate invasions. First,the cross section of the tunnel is measured and the clearance is checked. Then,tunneling invasion limits are reduced to meet the clearance requirements by means of fine-tuning of the line and slope. This paper,based on the circular tunnel,introduces the whole process of line and slope fine-tuning,summarizes details of adjustments and design fundamentals. |
