混凝土桥梁结构的耐久性优化设计

Optimum Durability Design of Concrete Bridges Structures

以常遇大气环境下的混凝土桥梁为分析对象，以年均投资差额最大为优化分析目标，提出了混凝土结构耐久性优化设计方法，并通过算例进行了验证。

By taking the concrete bridges under usual natural environment as analysis objective, the optimum durability design method of concrete bridges is suggested by analyzing the maximum average yearly investment difference in this paper, and the method is proved by example.
