近年来,由于斜拉索出现各种损伤而导致的更换拉索的维修项目频繁出现,引发了人们对拉索运营寿命的关注。该文在广泛收集国内外斜拉索换索工程资料和拉索损伤研究文献的基础上,总结了影响斜拉索运营寿命的各种因素事件及其在拉索损伤病害形成机制中的作用,利用故障树分析法,确定了影响拉索运营寿命的主要因素事件、事故模式及其重要程度,可为斜拉索施工管理及运营期管养策略的制订和损伤拉索剩余寿命评估的相关研究提供参考。
In recent years, due to various damage caused by cable stayed in the replacement cable repair frequent, triggering people’s attention on the cable life. Based on the extensive collection of research data on cable stayed cables and cable damage at home and abroad, the paper summarizes the various factors that affect the service life of cable stayed cables and their roles in the formation mechanism of cable damage trains. Using fault tree analysis method, the main factors influencing the operation life of cable are identified, such as events, accident modes and their importance, which may be related to the construction management of stay cables and the establishment of tactics during the operation period and the assessment of the remaining life of cable for reference.
