摘　　要：将属性层次分析法与TOPSIS法相结合,可考虑不同评价指标的权重,提高评价的科学性和客观性,充分利用属性层次模型(AHM)的优点,避免TOPSIS法中权重分配可能出现的主观性影响。泾河大桥的拱圈分为独拱段和双拱段,拱圈在空间上呈Y字形。针对Y形主、副拱肋缆索吊装问题,开展了主、副拱分开吊装及同时吊装2种拱肋吊装方案研究,基于AHM-TOPSIS法对空间Y形钢箱拱桥2种吊装方案进行比较,通过桥梁有限元计算,模拟分析2种吊装方案,分别得到对应吊装方案对桥梁应力、结构稳定性等方面的影响,对比选出最佳施工方案,主、副拱分开吊装有明显优越性。The combination of attribute analytic hierarchy process and TOPSIS can consider the weights of different evaluation indicators,improve the scientificity and objectivity of evaluation,make full use of the advantages of AHM,and avoid the possible subjective influence of weight allocation in TOPSIS.The arch circle of Jing River Bridge is divided into single-arch section and double-arch section,and the arch circle is Y shape in space.Aiming at the problem of Y-shaped main-secondary arch rib cable hoisting,research was carried out on the construction scheme of separate hoisting and simultaneous hoisting for the main and secondary arches.Based on AHM-TOPSIS method,the two construction schemes of spatial Y-shaped steel box arch bridge were compared,and the two hoisting schemes were simulated and analyzed through finite element calculation of the bridge.The influence of the corresponding construction hoisting scheme on the stress and structural stability of the bridge is obtained respectively,and the best construction scheme is selected by comparison:The main and secondary arches hoisting separately has obvious advantages.
