在分析桥梁承载力评定方法现状的基础上,引进了模糊描述,提出了基于材质状况和模糊评判的既有预应力混凝土空心板桥承载力评定方法。依据实桥耐久性检测数据,分析了基于结构检算的桥梁耐久性模糊评定,结合检测数据对耐久性评定指标进行修正,最后以实桥为例进行了空心板桥承载力状况的评定。计算结果与试验数据吻合较好,表明所提方法客观、全面,可为同类桥梁的承载力评定提供参考和借鉴。
Based on the analysis of the status quo of bridge bearing capacity assessment methods, fuzzy description was introduced and a method to evaluate the bearing capacity of existing prestressed concrete hollow slab bridges based on material condition and fuzzy evaluation was proposed. Based on the test data of actual bridge durability, the fuzzy evaluation of bridge durability based on structure checking is analyzed, and the durability assessment index is corrected with the test data. Finally, the real bridge is taken as an example to evaluate the bearing capacity of hollow slab bridge. The calculated results are in good agreement with the experimental data, indicating that the proposed method is objective and comprehensive and can provide references for the assessment of bearing capacity of similar bridges.
