| 摘 要： | 现有的评价方法,大多采用确定性评价指标对在役桥梁的缺损状况进行评估.本文着重考虑结构性缺损,尝试采用模糊性评价指标对在役桥梁的缺损状况进行评估.通过建立可靠性模糊评价递阶层次模型,对评价模型中的模糊评价因素权重系数、模糊评价指标隶属度函数、模糊评价可靠性分布向量等方面进行了系统研究,提出了基于变量(评价指标)模糊性的在役钢筋混凝土梁桥、圬工及混凝土拱桥可靠性评估方法.经实例验证,本文方法总体可行.

| Abstract: | There are some problems that defect conditions of existing bridge we reealuation hierarchy models for concrete beam bridge and masonry or concrete arch bridge were established emphasizing on structural defects. Reliability evaluation method of existing bridge based on fuzzy variables was put forward through system researches on weights of item level and index level factors, membership functions of fuzzy evaluation indexes, and distribution vectors of fuzzy reliabili- ty evaluation. The example shows that the paper＇s method is feasible. |
