1) one-tunnel two-tracks
单洞双线
1.
2 Line projects of Iron Teheran subway, the author analyzes disadvantages of “Rail Arrangement Method" in the rail construction for one-tunnel one-track subway projects and features of one-tunnel two-tracks subway projects, and provides a new construction method, in which engineers can directly place assembled rails on the structural base floor of tunnels as temporary tracks of rail flat-cars.
依托伊朗德黑兰地铁一、二号线工程 ,针对地铁单洞单线采用的轨道施工轨排法存在的不足 ,根据单洞双线隧道的特点 ,提出了利用组装好的轨排直接铺设在隧道结构底板上作为轨道平板车临时轨道的施工新方
2) double-tracked-single tunnel
单洞隧道双线

4) single cavern and double-layer
单洞双层
1.
In order to avoid the dense pile foundations of line-plot tall buildings,parts of metro tunnel need to be constructed by single cavern and double-layer.
地铁隧道为避开沿线高大建筑物密布的桩基,部分段落需要采用暗挖法施工的单洞双层隧道通过,而此时地铁隧道穿越的地层条件复杂,围岩极其软弱,地下水位高,且隧道埋深较浅,其力学行为将和单个隧道大不相同。
6) sole hole double deck tunnel
单洞双层隧道
1.
Study on construction technology of sole hole double deck tunnel in underground railway
地下铁道单洞双层隧道施工技术研究
补充资料：腊月中游发生洞裴回之际见双白蝙蝠三飞洞门
【诗文】：
欲验发生洞，先开冰雪行。窥临见二翼，色素飞无声。
状类白蝙蝠，幽感腾化精。应知五马来，启蛰迎春荣。
露冕□之久，鸣驺还慰情。
