摘　　要：天平山隧道部分地段为炭质页岩或砂岩夹炭质页岩,围岩极其破碎、有大量渗水,易掉块和变形,变形过大造成隧道坍塌,通过试验在保证安全的前提下,提出经济合理的支护参数,既有利于控制成本,同时也加快了施工进度。Some sections of Tianpingshan tunnel are carbonaceous shale or sandstone with carbonaceous shale. The surrounding rock is broken with a lot of water seepage, causing easy chipping and deformation and excessive deformation can lead to tunnel collapse. On the premise of security, economic and reasonable support parameters are put forward through test, which can control the cost and accelerates the construction progress.

关 键 词：隧道 软岩 变形控制 快速施工
