摘　　要：鉴于初期支护是二次衬砌的基础,初期支护大变形的预防与整治是破碎松散地质条件下隧道施工的关键,针对初期支护大变形的危害,分析了某高速公路隧道初期支护大幅变形的原因,提出了初期支护大变形的整治措施。As early support is the foundation of the second lining,the prevention and renovation for large-scale deformation of early support have become the key to he excavation of soft surrounding rock tunnels. In the light of the harms in large-scale deformation of early support,this paper analyzes the cause of large-scale deformation of early support in a tunnel. The measures for renovation of large-scale deformation of early support are presented.

关 键 词：隧道 支护 变形 下沉 加固
