美国密苏里罗拉大学工程专业的师生们目前正在校园里建造一座试验桥,该桥既不用钢铁也不用混凝土,而是选用玻璃和石墨纤维组成的聚合膜材料,但与钢铁或混凝土大桥相比,它具有重量轻、强度高、寿命长等特点,其结构中的“灵巧”部分配有与监控中心联网的光导纤维传感器,管理人员只要坐在电脑前就可随时掌握有关桥梁结构载荷情况的所有数据。
Engineering students at the University of Missouri, Missouri, are currently building a test bridge on campus that uses either steel or concrete instead of polymeric membrane materials made of glass and graphite fibers. However, compared to steel or concrete bridges, It has the characteristics of light weight, high strength and long service life. The “smart” part of the structure is equipped with an optical fiber sensor which is connected with the monitoring center. Administrators can grasp the load of the bridge structure at any time as long as they sit in front of the computer All the data.
