在役桥梁质量安全管理

Quality and Safety Management of Bridges in Service

摘要: 为提高我国桥梁服役阶段的质量安全，查阅了相关文献，结合本人现场学习经历，提出了两点保证桥梁服役期间质量的方法，并且就桥梁常见病害总结了常规的修缮措施。首先要在桥梁关键位置设置24小时检测设备，实时收集、传输数据；再建立桥梁的BIM模型使得桥梁整体可视化，然后在该基础上建立LSTM和ARIMA数学模型预测桥梁病害，缩短病害从发生到修复的时间；最后就桥梁易发生的病害提出了规范、科学的措施，从而提高我国在役桥梁的质量安全。

Abstract: In order to improve the quality and safety of bridges in China’s service stage, I reviewed relevant literature, combined with my on-site learning experience, put forward two methods to ensure the quality of bridges during service, and summarized the conventional repair measures for common bridge diseases. First of all, 24-hour detection equipment should be set up at key positions of the bridge to collect and transmit data in real-time; Then establish the BIM model of the bridge to visualize the bridge as a whole, and then establish the LSTM and ARIMA mathematical models to predict bridge diseases and shorten the time from disease occurrence to repair. Finally, standardized and scientific measures are proposed for diseases that bridge is prone to improve the quality and safety of bridges in service in China.
