火损后斜拉索运营期间的技术状况检测

Test on Technical Condition during Period of Stayed Cable in Service After Fire Damage

为了解斜拉索的目前的运营情况,确保护桥梁的安全运营,对某桥A2~#斜拉索进行检测和评估,并提出维护建议;在检测斜拉索破损程度的基础上,分析斜拉索火损对斜拉结构影响,腐蚀失效估算,索力检测对斜拉索检测的影响,进而提出服役中的拉索的维护建议。

To understand current operation of the cable,and ensure safety operation of the bridge,check and evaluate A2# cable of a bridge,and then make proposal for maintenance; On basis of detecting the damaged condition of cable,analyze effect of fire damage of the cable on the cable-stayed structure,the corrosion failure estimation and effect of the cable tension test on the cable test,to make the maintenance proposal for the cable in service.
