摘要
为解决因地震或人为因素造成的简支梁高架桥垮塌事故,研究了一种通过敷设普通光纤,实现桥面垮塌可靠实时检测和预警的系统。实验室桥梁模型实测结果表明,当光纤弯曲半径在6-10mm变化时,光强参数变化明显,可监测桥面结构件移位程度。
In order to reduce those calamities caused by earthquake and factitious factor which resulted in viaduct＇ s collapse and distortion, a real - time monitoring system was studied and presented by laying ordinary optical fiber along viaduct. The outcome based on actual experiments showed that the monitoring effect was reliable; when optical fiber＇ s bending radius changes between 6mm and 10mm, the light intensity＇ s parameter changes sharply at the same time, so the degree of the bridge＇ s displacement can be detected.
