摘　　要：隧道工程结构面临的环境因素较为复杂,因为隧道长期处于侵蚀性环境中,其混凝土结构的耐久性可能发生退化,这严重影响隧道的质量。本文综述了隧道混凝土耐久性的分类及影响原因,明确了隧道混凝土耐久性的形成因素及破坏形式,提出在实际工程中应采用不同的策略去应对,为指导实际工程,提高混凝土耐久性,提供了一些参考。The environmental factors faced by tunnel engineering structures are more complicated,because the durability of the concrete structure of the tunnel may be degraded due to its long-term erosive environment,which seriously affects the quality of the tunnel.This paper summarizes the classification of tunnel concrete durability and its influencing cause,clarifies the forming factors and failure forms of tunnel concrete durability,puts forward that different strategies should be adopted in practical engineering,and provides the suggestions for the guidance of practical engineering and improving the durability of concrete.
