| 摘 要： | 桥梁加固设计方案的选择既是一个技术问题,又是一个经济问题.运用工程经济学的基本原理,对既有桥梁加固在其寿命周期内可能产生的各项费用进行了详细的对比分析,建立了桥梁加固的经济分析比选模型,提出了桥梁加固的经济评价方法.最后例举工程实例说明方案比选过程,由计算结果可知：此方法能较准确地反映桥梁加固工程的经济效果,能够为既有桥梁改造方案的合理选择提供参考.

| Abstract: | The choice of bridge strengthening design is a technical question and even more economic question.Making use of the basic principles of engineering economics,every possible cost of the reinforcement for the current bridge during the life cycle has been analyzed.The economic analysis comparative model of the bridge strengthening has been made.The economic assessment method for bridge strengthening has been put forward.At last,an engineering example is given to show the process of comparing schemes.The calculation result indicates that this method can exactly evaluate the economy of bridge strengthening and give some references to select reasonable reconstruction scheme for the current bridge. |
