南京长江第三大桥主桥为钢塔双索面斜拉桥。介绍以有限元模型分析结果为基础,基于神经网络及遗传算法的全桥传感器测点优化布置理论,最终形成的该桥结构健康监测系统的传感器测点布置。
The main bridge of the 3rd Nanjing Changjiang River Bridge is a steel pylon and double cable plane cable-stayed bridge. This paper presents the theory of optimal placement of the sensor measurement points of overall bridge based on the analysis results of finite element model, the nerve cell network and generalized genetic algorithm, and also gives the finalized placement of the sensor measurement points for structural health monitoring system of the Bridge .
