桥梁结构现有技术状况的模糊综合评判

Fuzzy Comprehensive Evaluation on Existing Technical Condition of Bridge Structure

传统的桥梁结构技术状况评价主要依靠结构的强度、稳定性、刚度及其裂缝等方面的信息,运用调查、检测和验算相结合的手段,对现有桥梁的承载能力及使用条件做综合评定。该文借鉴模糊数学的原理,通过建立综合评判模型,确定隶属函数和权重,用模糊综合评判的方法来对桥梁做出一个比较客观的评价,并通过袂花江大桥的例子来分析说明。

The traditional evaluation on the technical condition of the bridge structure mainly de- pends on the information of the structural strength, stability, rigidity and crack by the means of in- vestigation, detection and check to carry out the comprehensive evaluation on the bearing capacity and using condition of the existing bridges. Referring the fuzzy mathematical principle and setting up the comprehensive evaluating model, the article determines the affiliation function and weight, uses the fuzzy comprehensive evaluation method to make a more objective evaluation on the bridges, and analyzes and explains it by the example of Meihua River Bridge.
