本文针对现有中、短跨钢筋混凝土桥梁的状态评估问题，提出了一种新的监测方法，即利用公共汽车作为公共交通系统的一部分，（总线监控系统），沿着安全指标，即特征偏差，其相对不受由于诸如路面粗糙度和结构异常参数等因素而引起的动态扰动的影响。利用技术验证实验和数值分析模拟的结果进行了基础研究。作为验证该系统的具体实例，详细介绍了如何通过宇部市公交网络上运行时测得的公交车振动来评估桥梁状况，以及在国外将该系统应用于既有桥梁时需要考虑的问题。
In this study, as one solution to the problem for condition assessment of existing short and medium span reinforced/prestressed concrete bridges, a new monitoring method using a public bus as part of a public transit system (bus monitoring system) is proposed, along with safety indices, namely, characteristic deflection, which is relatively free from the influence of dynamic disturbances due to such factors as the roughness of the road surface, and a structural anomaly parameter. A basic study was conducted by using the results of technical verification experiments and numerical analysis simulation. This paper describes the details of not only how to assess the bridge condition by public bus vibration measured in operating on Ube City bus network as a specific example for verify the system but also what kind of consideration we need to apply the system to existing bridges in overseas country.
