摘要
在桥梁运营期间,由于各种原因,会造成其不同程度的损伤和破坏。为了保证既有桥梁的安全运营和尽可能延长它的正常使用年限,应对其进行实时健康监测与安全性评估。以东营黄河胜利大桥为背景,提出了采用 GPS与全站仪相结合的健康监测方法,阐述了整个监测方案的具体实施过程并对观测数据进行了初步分析,对试验进行了总结,并对未来研究方向提出了建议。
During the service period, bridges may suffer from different degrees of damage and destruction due to various kinds of loads. In order to make the existing bridge safety operation and extending its safe service period, the bridge health monitoring and safety assessment should be done in a real-time way. In this paper, a new and practical method for the structural health monitoring by the integration of GPS and total station technology are first proposed for Yellow River Shengli Bridge. Then, the process of implementation of the method and measured data processing are presented in details. Finally, the processes of test are summarized and future research directions are suggested based on the above analyses and discussions.
