【摘要】：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。
[Abstract]:In recent years, the repair projects of replacement cables caused by various damage of stay cables appear frequently, which has aroused people's attention to the service life of cables. Based on the extensive collection of domestic and foreign data on cable replacement projects and the research literature on cable damage, this paper summarizes the various factors affecting the service life of stay cables and their role in the formation mechanism of cable damage diseases. By using the fault tree analysis method, the main factors affecting the service life of the cable, the accident mode and its importance degree, are determined. It can be used as a reference for the construction management of stay cables, the establishment of management strategy and the evaluation of residual life of damaged cables.
