摘要
针对空心板梁铰缝检测,通过先进的非接触式多点位移检测系统,采用铰缝相对位移与空心板挠度的比值作为评价指标,测试分析了在不中断交通的情况下某实桥空心板梁铰缝相邻处的各点挠度,并对铰缝作出损伤评估。研究表明,非接触式法评定空心板梁铰缝损伤度具有方便性和快捷性,测试结果可行,有一定的工程实际应用价值。
In this paper,the hollow seam girder seam detection,combined with advanced non-contact multi-point displacement detection system,the ratio of the relative displacement adjacent to hinge joint and the general deflection of hollow slab is defined as the evaluation index to describe the damage degree of hinge joint. The deflection of the joints at the adjacent joints of a hollow slab beam is analyzed and the damage assessment is made. The results show that the non-contact method can be used to evaluate the damage degree of the hollow slab beam. The test result is feasible and has practical engineering value.
