地下结构耐久性研究现状及发展方向综述

Summary of Actuality and Development Trend of the Research on Underground Structure Durability

早期地下结构的耐久性问题为人们所忽视,极少针对其展开专门研究。随着地下空间的进一步开拓和各类耐久性问题的日益严重,已开始引起世界各国的广泛关注。文章从地下结构耐久性研究的重要性、国内外对其开展研究的现状和不足、地下结构与地面结构耐久性的异同、今后重点研究方向几个方面进行总结和探讨。尤其强调从结构与力学层次和多因素影响机制角度进行分析。文章旨在讨论、交流和促进对地下结构耐久性问题的认识和研究。

In the early ages, the durability of underground structures＇ was neglected and scarely studied, so there are few data about it. With the further exploitation of underground space and increasingly severity of durability problem appeared, many countries start to analyze underground structures＇ durability and carry out lifetime prediction. In this paper, these problems are summarized and expatiated as follows： the importance of study on underground structures＇ durability, the study actuality and shortages in the study both at home and overseas in this field, its relation with the ground structures＇ durability, the problems that should be solved emphatically and principal study directions for the future. It is emphasized specially that the study should be done from structural and mechanical level and from the angle of multi - factors influence. This paper aims of discussion, communication and promotion of the study and understanding of underground structures＇ durability.
