摘要
斜拉索是现代大跨度斜拉桥的重要承重结构,由于其长期暴露在空气当中,比较容易受到各种腐蚀破坏,因此对其进行结构健康检测及安全评价非常必要。通过对斜拉索的健康检测及安全评价系统构建进行研究,提出在该检测及评价过程中,需要选择比较经济、耐用且稳定性强的检测装置,同时建立科学、合理、全面的评价系统,以全方位提高斜拉索桥梁的运营管理水平,维护桥梁的安全性和平稳性。
The cable is a major load-bearing structure for the cable-stayed bridge.Due to its long-term exposure to air,they are more susceptible to a variety of corrosion damage.So its structural health monitoring and safety evaluation is necessary.Based on the specific research for the detection of the health of cable and safety evaluation,the paper puts forward that in the process of testing and evaluation,it need to choose more economical,durable and strong stability of the detection device,and to establish a scientific,rational,comprehensive evaluation system to improve the cable-stayed bridge operational management,maintenance,bridge safety and smoothness.
