摘要
中承式钢管混凝土提蓝拱桥是一种新兴的桥梁形式,本文根据结构的振动信号分析对其损伤进行检测与评估这一检测技术,对四川内江新龙坳提蓝拱桥吊索固有频率进行测试与分析,并进一步对吊索的静张力进行了计算。这些测试与分析,是对桥梁进行损伤检测与评估的重要的组成部分,由此可得到桥梁维修与加固的科学可靠的依据。
The steel pipe concrete 'Basket Handle' type arch bridge is a new bridge type. Based on the testing technology using structure's vibration information, in this paper, the Xinglongao arch bridge's suspended cable inherent frequency was tested and analyzed and the computing method for static tensile force was introduced. Hence the whole construction damage could be inspected and evaluated, these test and analysis are the important part of the damage inspection and evaluation of a bridge and the scientifically reliable evidence for maintenance and reinforcement of the bridge can be obtained.
