摘要: 根据桥型设计方案资料,对包含定性指标的桥型方案进行客观评价。以马洋大桥设计方案为研究案例,根据两级模糊识别原理,提出定性指标相对隶属度确定方法,采用多目标最大距离法计算指标权重,建立基于两级模糊识别的桥型方案优选模型。优选结果为矮塔斜拉桥方案,符合客观实际。

关键词: 桥型方案, 模糊识别, 权向量, 相对隶属度, 多目标最大距离法

Abstract: Based on information of bridge type design scheme,objectively evaluates the bridge type scheme including qualitative index. Taking the design schemes of Mayang New Bridge as an research object, propose the method for qualitative index to solve relative membership grade.Multi-objective maximum distance method is introduced into the calculation of the index weight.Based on two-extreme fuzzy recognition theory,optimization of bridge type schemes model is established. The short tower cable-stayed bridge is the optimized outcome which is consistent with the objective reality.

Key words: bridge type scheme, fuzzy recognition, weight vector, relative membership grade, multi-objective maximum distance method
