摘要
深圳地铁重叠隧道是国内第一个整座区间采用锚喷构筑法施工的地铁隧道,该隧道所处地质条件差、与周围建筑关系复杂,设计施工难度大。六年前,为了达到安全、可靠、经济的目标,集中了国内相关技术力量,对重叠隧道工程的设计与施工开展了一系列研究,解决了许多关键性技术难题,探索出了一套先进、科学的设计方法和施工工艺,确保了该隧道按期顺利建成。隧道已经过近2年的运营,目前状态良好。为了推广应用其建设经验,文章对重叠隧道设计、施工中的关键技术进行了总结。
The overlapped tunnel in Shenzhen metro is the first metro transit tunnel in China that was build by using rock bolts and shotcrete technology. The tunnel is featured by its poor geological conditions, complicated surroundings with many surface buildings and difficulties in design and construction. The tunnel was build six years ago and has been operated for near two years under good conditions. The paper summarized the key techniques in the design and construction of the overlapped tunnel in the hope of extending the application of the accumulated experience of its construction.
