【摘要】 润扬长江公路大桥作为我国建桥史上规模空前的特大型桥梁 ,对其建设和运营期间的健康监测、诊断以及各种灾害影响下的损伤预测和损伤评估 ,具有重要的现实意义 ,这也是润扬大桥设置结构安全健康监测系统的主要目的。作为该系统所要解决的最关键问题之一 ,就是合理解决传感器测点的最优布置。基于这一考虑 ,详细介绍了以有限元模型分析结果和基于广义遗传算法的主梁传感器测点优化布置为主要理论依据 ,最终形成的润扬大桥结构安全健康监测系统的传感器测点布置。更多还原

【Abstract】 Runyang Yangtse River Highway Bridge is the longest bridge at present,it is prac tically significant to health monitoring, diagnosis, forecast and evaluation of injury influenced by disasters, during its building and working, also, it is the purpose of the Health Monitoring System of Runyang Bridge. As one of the most i mportant problems of the system, optimum placement of sensor must be sloved rati onally. From this point of view, in detail this paper introduces the primary aca demic gist, which contains analytic result of finite element model and optimum p lacement of sensor in girder based on generalized genetic algorithm, and sensor placement for the Health Monitoring System of Runyang Bridge.更多还原
