摘　　要：隧道高应力及软岩大变形是隧道施工面临的施工难点之一,为确保隧道施工的稳定有序,必须依据地质勘探结果制定科学合理的施工方案。该文以某铁路隧道为例,基于施工面临的大埋深、高应力、破碎软岩等地质条件,对隧道施工大变形的主动支护施工方案进行探讨,并对施工环节重点进行分析,旨在为类似隧道施工提供参考。High stress and large deformation of soft rock are one of the difficulties in tunnel construction.In order to ensure the stability and order of tunnel construction,a scientific and reasonable construction scheme must be formulated according to the results of geological exploration.Taking a railway tunnel as an example,based on the geological conditions such as large buried depth,high stress and broken soft rock faced by construction,this paper discusses the active support construction scheme of large deformation in tunnel construction,and analyzes the key points of construction links,aiming to provide reference for similar tunnel construction.
