考虑不确定性因素的桥梁结构建模技术分析

摘要

The diagnosis problem of safety status for bridge structure in construction stage is analyzed. From two angles of the uncertain factors and the structural modification,the modeling technology of bridge structure at this stage is further elaborated. Based on the modification of the interval finite element model and the fuzzy finite element model,specific modeling methods are summarized,and the future research direction is studied.%针对桥梁结构在施工阶段中安全状态的诊断问题，从不确定性因素和结构优化修正两个角度出发，阐述了现阶段的桥梁结构建模技术，基于区间有限元模型和模糊有限元模型的修正，归纳总结了具体的建模方法，并对今后可行的研究方向进行了思考。
