摘要
以城市现役混凝土简支梁桥、连续梁桥、连续刚构桥梁为研究对象,针对现有规范和文献关于桥梁评估方法存在的问题,结合静载和动载实测数据采用模糊综合方法判断桥梁的实际承载能力状况,提出了静动载试验的模糊综合评价方法,构建了静动载试验层次结构评估模型,对评估指标进行了模糊量化,构造相应的判断矩阵,并计算各层次因素的权重值。最后对提出的方法进行工程实例验证。
The static/dynamic loading experiment should be carried out when the evaluation results are far from satisfaction or when special conditions need to be satisfied.The research objects of this paper are urban concrete simply supported beam bridges, continuous beam bridges and continuous rigid frame bridges.Fuzzy evaluation method based on static/dynamic loading experiment is studied.The experimental results are then employed in fuzzy evaluation to estimate the actual loading capacity of bridges to meet the need for fast estimating and evaluation quality for urban bridges on active service.
