基于定期监测钢筋混凝土箱型系杆拱桥索力分析研究

Cable Force Analysis of Reinforced Concrete Box Arch Bridge Based on Regular Monitoring

以某钢筋混凝土箱型系杆拱桥为工程背景,在系杆和吊杆锚固端安装索力测试传感器,定期对其系杆和吊杆索力进行监测,通过对比分析索力变化趋势,并对其病害进行了跟踪监测,结果表明大桥在运营期间吊杆和系杆索力正常,但需要对结构性病害及时进行维修和保养。

A reinforced concrete box arch bridge as the engineering background,installation testing sensor cable force in the tie and the steeve anchoring end,periodically monitored the tie and steeve cable force,through the comparative analysis of change trend of cable force,and the disease was monitored,the results show that the bridge steeve and tie cable force was normal during the mornitoring period,but the need for structural disease timely repair and maintenance.
