面向吊索损伤识别方法研究的拱桥实验模型设计

Design of Test Model of Arch Bridges for Hanger Damage Identification

桥梁损伤模拟实验一般无法直接在实桥上进行,故整桥模型实验在桥梁损伤识别研究中尤为重要。根据基于系梁挠度进行拱桥吊索损伤识别方法研究的模型实验目的和要求,提出了该类实验模型设计的原则和吊索损伤的模拟方法,设计了一套面向吊索损伤识别方法研究的系杆拱桥实验模型。实验结果表明,该套实验模型完全可以满足基于系梁挠度的拱桥吊索损伤识别方法研究的各项实验要求,其设计思路和方法对其他桥梁损伤模拟实验研究具有参考意义。

Generally speaking,the bridge damage simulation test cannot be carried out directly on the actual bridge.Hence,the whole bridge model test is critical in the research of bridge damage identification.Based on damage identification of hangers based on deflection of the tie-beam,a set of the test model of tied-arch bridge was designed.The principle of test model design and the simulation methods of hanger damage was put forward.The testing results show that the test model can fully meet the test requirements,and its design ideas and methods are of reference significance for other bridge damage simulation tests.
