大跨桥梁结构状态评估方法研究进展

Progress in condition assessment methods for long span bridges

简要回顾了国内外结构状态评估理论的发展 ,在此基础上 ,对蒙特卡罗法、层次分析法等桥梁结构常用的状态评估方法进行了介绍和比较 .结合润扬大桥悬索桥 (国内最大跨度的悬索桥 )及苏通大桥 (世界在建最大跨度的斜拉桥 )中的状态评估系统 ,介绍了该系统的功能以及模块构成 .最后阐述了状态评估领域的主要研究问题和发展方向 .

The progress in structure condition assessment is briefly reviewed, and based on this, the general methods of bridge condition assessment are introduced and compared, including Monte Carlo method and analytical hierarchy process, etc. Combined with the introduction to the condition assessment system on Runyang Bridge which is the longest suspension bridge in China and Sutong Bridge which is the longest cable-stayed bridge in the world, the function and its constitution of this system are discussed in detail. The main problems in probability analysis and the development of condition assessment are presented.
