加固方案的选择是旧桥加固设计的关键环节,选择加固方案涉及的因素众多,且部分因素具有模糊性,从而在确定加固方案时采用了多级模糊综合评判决策方法进行优选。本文针对拱桥加固的特点,结合具体的拱桥实例,采用了二级模糊综合评判决策方法进行加固方案的优选,并详细介绍了该方法的应用模型,结果表明,这一方法计算简单,具有很大的实用价值。
The selection of reinforcement scheme is the key link in the reinforcement design of old bridge. There are many factors involved in the selection of reinforcement scheme, and some of the factors are ambiguous. Therefore, multi-level fuzzy comprehensive evaluation decision-making method is selected to determine the reinforcement scheme. In this paper, according to the characteristics of arch bridge reinforcement, combined with concrete arch bridge examples, the second-level fuzzy comprehensive evaluation decision-making method is used to optimize the reinforcement scheme. The application model of this method is introduced in detail. The results show that this method is simple and has a large The practical value.
