【摘要】：钱塘江大桥于1937年9月建成通车,是由我国著名桥梁专家茅以升设计并主持施工的第一座双层式公铁两用特大桥,已被国务院批准列入第六批全国重点文物保护单位名单,目前仍承担着铁路运输任务。大桥安全监测系统采用传感器、信号处理、网络通信、计算机及数据分析处理技术,对梁、墩关键部位的振动、应力、位移进行长期监测,并依据规范对桥梁安全状态进行评估。本文介绍钱塘江大桥安全监测系统的基本构成、测试数据分析与安全评估方法。该系统实现了基于桥梁结构实时响应的桥梁安全监测,为铁路老龄桥、病害桥和重点桥梁的运营管理、养护维修提供了一种新的技术手段。
[Abstract]:The Qiantang River Bridge, which was completed and opened to traffic in September 1937, is the first double-deck highway and railway bridge designed and constructed by Mao Yisheng, a famous bridge expert in China. It has been approved by the State Council to be listed as the sixth batch of national key cultural relics protection units. At present, it is still undertaking the task of railway transportation. The bridge safety monitoring system adopts the technology of sensor, signal processing, network communication, computer and data analysis and processing to monitor the vibration, stress and displacement of the key position of beam and pier for a long time. The safety state of the bridge is evaluated according to the specifications. This paper introduces the basic structure, test data analysis and safety evaluation method of Qiantang River Bridge safety monitoring system. The system realizes the bridge safety monitoring based on the real-time response of bridge structure, and provides a new technical means for the operation management, maintenance and maintenance of railway aged bridges, diseased bridges and key bridges.
