| 摘 要： | 一座结构寿命终止并非指结构已经倒塌破坏。提出了基于可靠性与经济优化相结合的在役混凝土结构剩余使用寿命的评估准则 ,并建立了在役混凝土结构剩余使用寿命预测的优化模型。通过对该模型的求解 ,可以为维护与加固结构的合理决策提供参考。

| Abstract: | It doesn't mean collapse for a structure while reaching its end of the life.In this paper,an assessment criterion for remaining service life of existing concrete structures is put forward based on theory of reliability and economic optimization.And also,an optimum model of how to predict the remaining life is provided,which can offer a proper reference for decision\|making. |

| Keywords: | concrete structures\ reliability\ economic optimization\ remaining service life |
