摘　　要：由于不可拆解的超长、超宽、超重的大件货物运输对桥梁的要求较高,为了大件运输和桥梁的安全,从大件运输中桥梁加固工程的特点出发,通过类比分析简支梁桥的各种加固方法,在考虑便捷性前提下选取安全性、经济性、时效性因子作为评价指标,并利用计算机科学技术手段,采用数据包络分析法对加固方法进行综合评价,经MaxDEA分析确定了投入主导型的C2R模型,最终计算得到了大件运输简支梁桥加固方法的优先序列,为实际工程中方法的优选提供了必要的理论依据.Because bulky cargo transportation has characteristics that extra-long, extra-wide, overweight and not disassembled, it has high requirements on bridges. For the safety of large transportation and bridges, departure from the characteristics of bridge reinforcement project in large transportation, analyzing a variety of reinforcement methods of simple beam bridges, in considering convenience premise, we select security, economy, timeliness as the evaluation index, using the technology of computer science and the method of data envelopment analysis, we have a comprehensive evaluation of bridges reinforcement methods. By the analysis of MaxDEA, we dominated the invest oriented C2R model, eventually calculated the priority sequence of reinforcement method,providing the necessary theoretical basis for the preferred method in practical engineering.
