摘要
云中山隧道进口段右线围岩变化频繁,开工后工程进度一直呈滞后状态。为此,工程单位决定从横洞增辟工作面的隧道开挖,其施工安排、出渣作业、通风、排水等均与普通隧道不尽相同,对此进行探析可供类似工程参考。
was The right line surrounding rock in inlet section of Yunzhongshan tunnel changes frequently. It lagging behind the progress after the project has been started. Therefore the engineering units decided to add working face from the cross-hole. It is different from the ordinary tunnel, such as implementation arrangements, mucking operations, ventilation, drainage, etc.
