摘要:
结合共和隧道工程施工实例,介绍在高地应力和顺层偏压等综合作用下,围岩初期支护大变形特点,分析这种特殊地质病害的原因,并通过各种施工方案的对比,提出合理的处理措施及后续施工对策。同时,简要阐述初期支护大变形段的处理技术措施,为今后同类型地质病害的隧道制定施工方案提供一定的借鉴。

Abstract:
Due to the action of high ground stress, bedding strata and unsymmetrical loading, huge deformation occurs to the primary reinforcement structure of Gonghe tunnel during construction. The features of the deformation are presented, the causes for such geological diseases are analyzed, different construction options are compared and proper construction countermeasures are proposed. The treatment of the huge deformation is described. The paper can be served as reference for the determination of construction schemes for tunnels in similar geological conditions in the future.
Key words: tunnel, high ground stress, primary reinforcement, huge deformation, treatment technology
