为满足我国公路交通运输事业快速发展的需要,在新建高等级公路的同时,改建许多旧有已建低等级公路成为目前公路建设中一项重要任务。在改建中,对运营多年的已建桥梁结构的耐久性进行评价,是决定该桥是否能够继续使用的重要依据,同时,对于新建桥梁结构耐久性的评价也是衡量其是否能达到预期运营年限的重要指标。文章即以模糊评判为基础,以实桥检测为例,建立桥梁耐久性的多级模糊综合评价体系。
In order to meet the needs of the rapid development of China’s highway transportation and transportation, it is an important task for the existing highway construction to reconstruct many existing low-grade highways when new high-grade highways are built. In the reconstruction, the evaluation of the durability of the bridge structure that has been operating for many years is an important basis for determining whether the bridge can be used continuously. At the same time, the evaluation of the durability of the new bridge structure is also a measure of whether the bridge can reach the expected operating life Important indicators. The article is based on fuzzy evaluation, taking the real bridge test as an example, the multi-level fuzzy comprehensive evaluation system of bridge durability is established.
