摘　　要：在隧道的建设发展过程中,隧道快速施工已经成为主要的趋势。本文以毛蓬岗隧道施工工程为例,介绍了变截面大跨度隧道施工过程中的总体施工方案,包括施工关键技术、施工内容,其中详细介绍了二次衬砌施工工艺流程,实践表明,二次衬砌施工使得毛蓬岗隧道在施工工期内顺利建成,这种施工技术不仅能够提高施工效率,还具有明显的经济效益,对变截面大跨度隧道的快速施工提供较高的参考价值,值得推广。During the construction and development of tunnels, rapid tunnel construction has become a major trend. Taking the construction of Maopenggang tunnel as an example, this paper introduces the overall construction plan of the construction process of variable-section large-span tunnel, including the key construction technology and construction content. The process of secondary lining construction is introduced in detail. The lining construction makes the Maopenggang tunnel successfully built during the construction period.This construction technology not only improves the construction efficiency, but also has obvious economic benefits. It provides a high reference value for the rapid construction of the variable-section large-span tunnel and is worthy of promotion.
