摘要
通过比较加固桥梁与新建桥梁诸多方面的差异,对加固桥梁和新建桥梁的生命周期成本进行了横向对比分析,采用年值成本差(ACD)和年值成本比(ACR)两个经济指标评价桥梁加固工程的经济性。提出了基于桥梁加固工程生命周期成本分析的评价方法,并给出了应用算例,由计算结果可知该方法能较准确的反映桥梁加固工程的经济效果。
The paper researched the many-sided difference of strengthening and new bridge, and transversely analyzed the life-cycle cost of strengthening and new bridges. Two economic indicators (ACD and ACR) are adopted to evaluate the economy of bridges strengthening. This paper presented an evaluation method based on life-cycle cost analysis of bridges strengthening, and given a computational example. The calculation result indicates that this method can exactly evaluate the economy of bridges strengthening.
