| 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。

| Abstract: | Based on information of bridge type design scheme,objectively evaluates the bridge typescheme including qualitative index. Taking the design schemes of Mayang New Bridge as an re-search 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 estab-lished. The short tower cable-stayed bridge is the optimized outcome which is consistent with theobjective reality. |
