桥梁建筑中长期承载物流车辆后的变形分析

Analysis of Bridge Deformation Under Loading Pressure form Logistics and Vehicles for The Medium and Long Term

在一些物流产业发达的城市,桥梁受到大型物流车辆的周期性碾压的影响,会发生局部的断面挠度形变。传统的GPS定位测量技术,在检测中依靠形变部位的坐标值进行形变检测,转换后的坐标误差会导致形变特征对应不准,造成检测的准确性不高。提出一种基于ANSYS有限元模型误差补偿技术的大跨度桥梁结构的承载力检测方法,并提出了CFRP加固方法进行修复。实验结果表明,这种算法能够提高桥梁在高压力下的承载力检测准确性。

In some of the logistics industry developed city, bridge is affected by the periodic rolling of large logistics vehi-cles, partial section deflection deformation will happen. The traditional GPS measurement technology, rely on deformation in parts of the deformation coordinate values and the transformed coordinates error will lead to deformation characteristics corresponding to no, cause detection accuracy is not high. This paper proposes a complementary technology based on AN-SYS finite element model of the bearing capacity and repairing CFRP strengthening method is proposed. Experimental re-sults show that this algorithm can enhance the bearing capacity of Bridges in the high pressure detection accuracy.
