摘要
近年来,随着我国经济和社会的发展,城市交通流量与日俱增,荷载超限情况也非常普遍,这使得我国城市桥梁安全面临着巨大的挑战。随着桥梁事故频发,社会各界对桥梁安全问题越来越重视。为了尽量避免事故发生,城市桥梁的检测工作的重要性日益突出。现以某一座城市跨线桥为实例,对城市桥梁进行技术状况检测和荷载试验的方法进行研究,并就桥梁实际情况,对桥梁进行了梁端斜截面裂缝专项检测和铰缝损伤专项检测,并对桥梁给出后续处理建议,为类似状况的城市桥梁检测和荷载试验提供借鉴和参考。
In recent years,with the development of the economy and society in China,the urban traffic flow increases every day and the overload limit is also very general,which makes the safety of urban bridge face the huge threat in China.With the frequent bridge accidents,all sectors of society more and more pay attention to the bridge safety.In order to avoid the accident frequency as much as possible,the significance of urban bridge detection is more and more important.Taking an urban overpass as an example,the article studies the technical condition detection and load test methods of urban bridges,introduces the special detections of the diagonal crack and hinge joint damage at the bridge end by the actual situation of bridge,and gives the following treatment proposals for the bridges,which can be referred for the detection and load test of the similar urban bridges.
