%X 传统的桥梁裂缝检测方法耗时耗力，效率低，且存在漏检等情况。本文对新型的基于光纤传感器的桥梁检测方法进行了研究，包括F-P光纤传感器、布拉格(Bragg)光栅传感器、光纤AE传感器等，最后介绍了光纤光栅解调仪对桥梁裂缝的检测，该套设备能有效检测出桥梁裂缝所在位置。<br />
The traditional bridge crack detection methods are time-consuming and inefficient, and there are some problems such as missing detection. In this paper, new bridge detection methods based on fiber sensors are studied, including F-P fiber sensor, Bragg grating sensor, fiber AE sensor, etc. Finally, the detection of bridge cracks by fiber Bragg grating demodulation instrument is introduced. This set of equipment can effectively detect the location of bridge cracks.
