基于耐久性的桥梁结构优化设计模型

The optimum bridge structure design based on durability

针对预应力混凝土桥梁结构 ,以全预应力混凝土受弯构件为例 ,对考虑耐久性的桥梁结构优化设计方法进行了讨论分析 ,并给出了相应的结构选型及优化设计的数学模型 ,为进一步的工作提供了理论基础。

Aim at pre-stressed concrete bridge structures, the optimum design method that consider durability is analysis. And take example of pre-stressed concrete bending member, the relevant math model of structure type and optimum design is given, which give a theory basis for the further research.
