摘要
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.文中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,并介绍了该方法的应用模型.
The selection of sheme is the key procedure in the reinforcing design of old bridge.Since some influential factors in the selection procedure are fuzzy,multistage fuzzy comprehensive evaluation method is used.Based on the characteristic of Arch Bridge,the two levels fuzzy comprehensive evaluation method is demonstrated and the mathematic model is introduced in detail along with some examples.
