| 摘 要： | 松桂1号隧道出口正洞穿越深埋炭质页岩地层,该地层由于受到地质构造及炭质页岩地层特性的影响,在施工过程中表现为不同形式的应力变形。经过对围岩地质构造和该类围岩实际开挖支护形式的探讨研究,以及支护措施加强适应性研究和施工方案的选择,总结出了一套安全、快速通过此地层的应对方案及措施,积累了施工经验,为今后此类工程提供了借鉴。

| Abstract: | The 1# exit straight tunnel of Songgui is passing through the deep-buried carbonaceous shale,which presents different forms of stress-deformation in the progress of construction,for the influence of both geologic formation and characteristics of carbonaceous shale.After discussed and studied on the geologic formation of surrounding rock,the support format of surrounding rock in real excavation,the applicability of support measure,and the selection of construction scheme,the author summed up a set of schemes... |
