摘要 采用有限元通用程序ANSYS对该桥进行静力与动力分析确定传感器的布设位置,并依据计算的前20阶动力特性结果,采用遗传算法(GA)进行传感器的优化布设,选用精度较高的光纤光栅传感器,能够满足对桥梁长期监测的需要。 Places of sensor is according to the static and dynamic analysis by the process of ANSYS. According to the finite element computing results of 20 pre-grade dynamic character, we use the GA to optimize the place of sensors. The fiber optics sensors are used in the case, they can do the need of monitor bridge for long period.
