摘要
结合青岛地铁一期3号线的清江路站工程,研究了在无围岩断裂带环境下隧道进行交叉段开挖时引起的围岩应力场和位移场的变化情况以及衬砌结构的施工力学行为.论述了围岩支护工艺、开挖速度、开挖方法和路面荷载对隧道开挖的影响.为同类工程施工提供借鉴.
Combined with Qingj iang Road Station Engineering of Qingdao Metro Line 3 of Phase I,the author of this paper studies the changes of enclosing rock stress field and displacement caused by the excavation of the tunnel cross-section under the construction environment of no enclosing rock fault,as well as the mechanical behavior of the lining construction.He also discusses the influence of enclosing rock supporting technology,excavation methods and road load on the tunnel excavation,providing reference for similar projects.
