大跨度斜拉桥变形观测的实施方法

Deformation Monitoring of Long-Span Cable-Stayed Bridge

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[1]。介绍了现代大跨度斜拉桥变形产生的原因、监测的内容、变形监测的实施方法,指出利用现代测量仪器和技术不仅完全可以满足大跨度桥梁管理部门提出的要求,而且还可以提高测量速度,其测量成果也具有很高的精度。

This paper discusses deformation causes of modern long-span cable-stayed bridge and its monitoring method of deformation and points out that using modern measuring instruments and technology not only can meet fully needs of the long-span bridges administration, but also can heighten measurement speed and accuracy.
