摘    要:基于青岛丹山水库混凝土斜拉桥,建立了斜拉桥有限元数值分析模型,确定桥梁受损后各子结构权重,选择典型斜拉索,对桥梁结构健康状态进行分析。首先运用通用结构分析软件对实桥建模,得到桥梁数值模拟试验模型及试验数据;再用正交试验选择典型斜拉索,大大减少了对桥梁分析计算的工作量;将桥梁分为3个子结构,用层次分析法确定各子结构权重,并建立了混凝土斜拉桥结构健康状态评估模型。结果表明,该模型能有效地对桥梁进行损伤评估和状态评估。

关 键 词:桥梁工程  混凝土斜拉桥  有限元  层次分析法  正交试验  健康状态  评估模型

Abstract:Based on Danshan concrete cable-stayed bridge in Tsingtao city,its 3-dementional finite-element model(3D FEM) is developed.In this model,the impact weights of every sub-structure in damaged bridge are calculated,the typical cables are selected,and bridge structure health condition is analyzed.The numerical simulating model and test data are gotten through 3D FEM of the bridge,the typical cables are selected by orthogonal experimentation method,so the analysis works are reduced greatly,the weights of the three sub-structures are calculated by Analytic Hierarchy Process(AHP) method;the concrete cable stayed bridge classification method is presented.The results show that this model are effective to evaluate bridge damage degree.(6 tabs,) 2 figs,6 refs.
Keywords:bridge engineering   concrete cable-stayed bridge   3D FEM   AHP   orthogonal experiment   health condition   assessment model
