摘要: 阐述了公路旧桥加固效果后评价的基本概念和内容体系, 在传统成功度评价法的基础上, 提出了成功度综合评价法用以评价桥梁加固后的综合效果。该方法应用层次分析法建立桥梁加固项目成功度综合评价指标体系; 采用德尔菲评分法确定评价指标集, 并根据指标类型的不同对其进行优化处理, 得到成功度综合评价矩阵; 对模糊数学理论的矩阵算子进行拓广, 建立了既全面考虑又兼顾重点的成功度综合评价计算模型。算例中双曲拱桥加固后项目成功度的计算结果为0 46, 成功度综合评价结论为“部分成功”, 与实际相符, 这说明成功度综合评价方法可综合专家的模糊评价信息, 能对桥梁加固效果作出合理的定性评价。Abstract: In order to evaluate bridge strengthening effectiveness, the paper put forward the conception and content system of post-evaluation of bridge strengthening effectiveness, based on the conventional success-degree evaluation method, set up the comprehensive success-degree evaluation model of bridge strengthening effectiveness. In the model, the evaluating indices system of success-degree for bridge strengthening was established by analytic hierarchy process, the indexing set of evaluating indicators was determined with the merits of Delphi method, and it was optimized according to the different types of indicators, hence comprehensive appraisal matrix was formed, the matrix operator of fuzzy theory was improved. Computation result of bridge evaluation is 0.46, comprehensive evaluation is part success, which accords with the bridge real situation, the model is feasible.
