摘　　要：综述了非路面式桥梁动态称重(B-WIM)30多年来的发展历史,重点介绍了B-WIM新方法。从基本理论与算法、工程应用、产品研发等几个方面总结了非路面式桥梁动态称重研究取得的成就与结论,分析了现阶段B-WIM存在的主要问题,为B-WIM今后的研究与发展提供参考。结果表明:精确检测车轴信息,拓展B-WIM的适用桥型范围,发展二维B-WIM方法和提高测试结果精度将成为今后重要的研究方向。The authors reviewed the non-pavement bridge weigh-in-motion （B-WIM） in last 30 years, especially the new B-WIM methods. Some research achievements were summarized in terms of several aspects, such as essential theory and algorithm, engineering application, product research and development, and the main problems about B-WIM at present were analyzed. The results show that accurate detecting of axle information, expanding the applicable scope of B-WIM, developing 2-dimensional B-WIM methods, and improving the accuracy of test are the important research issues in the future.
