工程结构的耐久性问题是一个特别重要且需要认真解决的课题,进行该项研究,一方面可以对已经投入使用的地下结构进行合理的耐久性等级评定和剩余寿命预测,以选择合适的处理方法和措施进行维护;另一方面也可以对即将新建的工程项目进行耐久性等级评估与寿命设计,揭示影响结构寿命的内外因素,对提高工程的设计水平和施工质量有特别实际的意义。
The durability of engineering structure is a particularly important issue that needs to be seriously solved. On the one hand, the durability structure of the underground structure that has been put into operation can be assessed on a reasonable basis and the residual life can be predicted to select the appropriate treatment method On the other hand, it is also possible to evaluate the durability level and life span of the newly-built project, reveal the internal and external factors that affect the life of the structure, and have particular practical significance for improving the design level and construction quality of the project.
