摘　　要：鉴于当前大跨径拱桥劲性骨架施工应用广泛,以及对劲性骨架施工定额编制的紧迫性,本文以缆索吊“斜拉扣挂+分环分段”法施工为基础,构建了基于AHP-模糊数学的施工定额编制模型。首先研究列举影响施工定额评价指标,然后选择与研究定额相关的5个已完建项目作为测定对象,并由AHP法确定评价指标权重,然后专家对测定对象评价指标打分,同时引入隶属度函数“梯形分布”确定隶属度,最后计算大跨径拱桥劲性骨架施工额定综合代表值。实例验证结果表明该模型具有可操作性和合理性。In view of the wide application of the current large-span arch bridges and the urgency of the construction of the rigid skeleton construction,this paper builds the AHP-fuzzy based on the construction of the cable-st ayed“slant-pull-hanging+sub-ring segmentation”method.Mathematical quota programming model.Firstly,the construction quota evaluation indicators are listed,and five completed projects related to the research quota are selected.The weights of the evaluation indicators are determined by the AHP method.Then the experts score,and the membership function“trapezoidal distribution”is introduced.Finally,the membership degree is determined and the calculation is integrated.Representative value.The example verification results show that the model is operational and reasonable.
