摘要
隧道施工特别是复杂地质条件下的施工面临着很多地质灾害问题,如岩溶地段的突水突泥、断层破碎带的塌方等,为了避免这些灾害事故的发生,开展岩溶隧道的施工技术管理研究,对于公路隧道施工具有重要的实际意义。针对湖北大广南高速公路建设中紫荆山隧道实际工程,阐述了紫荆山隧道施工过程中的超前地质预报方法,论述了隧道监控量测管理与分析方法,总结了隧道涌水段施工管理、防排水措施和安全应急预案等施工技术,对类似地质条件下的隧道施工具有一定的指导意义。
Geological hazard accidents often occur in the course of tunnel construction especially in the condition of complex geology,such as the water and mud rush in Karst region and the landslip of the faulted zone.In order to avoid such accidents,a study on the management of tunnel construction technology in Karst region was carried out,which was important for highway tunnel construction.According to Zijingshan tunnel construction of Daguangnan highway in Hubei province,several advanced geological prediction technologies are introduced and the management and analysis of tunnel monitoring are presented.The construction management of water rush section,drainage measures and safety emergency pre-arranged plan are summarized,which serves as some guidance to the work under similar geological condition.
