桥梁安全评价是当前道桥领域研究的热点问题之一。本文提出了基于直觉模糊集的桥梁安全评价方法,其中构建的计分函数考虑弃权者倾向赞成票、反对票和弃权票的比例的重视反对意见对决策的影响,更准确的反映方案评价中人的主观直觉。结合泗阳大桥梁设计方案进行评价,结果表明该方法可以客观科学地的进行桥梁安全评价,提高决策的可靠性。 Bridge safety evaluation is one of the hot issues in the current bridge area research. In this paper, a bridge safety evaluation method based on intuitionistic fuzzy set is proposed, in which the scoring function is constructed to consider the impact of the disagreees favoring the pro-vote votes, the negative vote and the abstention vote on the decision-making, and more accurately reflecting the mid- Subjective intuition. Combined with Siyang Bridge design program evaluation, the results show that the method can be objective and scientific evaluation of the bridge safety, improve the reliability of decision-making.
