摘　　要：为深入了解地下工程锚固结构的腐蚀影响因素及其作用机制,提高地下空间永久支护结构的耐久性和长期稳定性,通过梳理国内外文献,系统总结和分析了当前国内外在地下工程锚固结构腐蚀耐久性方面的研究进展和成果.指出了地下锚固结构腐蚀耐久性研究的必要性和紧迫性,简述了锚固结构应力腐蚀开裂机理及应力腐蚀评价方法,归纳总结了地下锚固结构腐蚀影响因素,论述了各影响因素的研究现状与作用机制,介绍了时效性分析和可靠性评估在锚固结构耐久性研究方面的应用.最后基于以上分析,对地下锚固结构腐蚀耐久性问题的发展趋势进行了多方面的展望,指出静态分析向动态分析转变、定性研究与定量研究相结合、单因素分析向多因素分析发展、宏观研究向微观研究深入、确定性分析向概率和随机性分析进化,是推动地下工程锚固结构腐蚀耐久性发展的重要研究方向.In order to understand the corrosion influencing factors and the mechanism of each influencing factor of anchorage structures in underground engineering and improve the durability and long-term stability of permanent support structures in underground space, the research progress and achievements of the corrosion durability of anchorage structures in underground engineering are summarized and analyzed by combing literatures at home and abroad. Firstly, the necessity and urgency of research on corrosion durability of underground anchorage structures are pointed out. Secondly, the stress corrosion cracking mechanism of anchorage structures and the evaluation methods of stress corrosion are briefly described. Thirdly, the influencing factors of corrosion of underground anchorage structures are summarized, and the research status and mechanism of each influencing factor are discussed. Fourthly, the application of time-dependency analysis and reliability assessment in the study of durability of anchorage structures is introduced. Finally, based on the above analysis, the development trend of corrosion durability of underground anchorage structures is prospected in many aspects. It is pointed out that the transition from static analysis to dynamic analysis, the combination of qualitative and quantitative research, the development from single factor analysis to multi-factor analysis, the further development from macroscopic research to microcosmic research, and the evolution from deterministic analysis to probability and randomness analysis are the important directions to promote the research on corrosion durability of anchorage structures in underground engineering.
