中文摘要：

根据光纤Bragg光栅（FBG）传感系统应用于某工程混凝土管桩测试的现状，对该传感系统的抗击打性能进行了试验评价，发现法兰盘接头和附近的区域最易发生破坏，数据连接线也易损坏，而FBG传感器最不易破坏。根据以上试验结果，提出了相应的减振措施，采用粘扣、塑料管、麻绳等手段进行保护，并通过试验验证了此种保护措施的减振效果。

英文摘要：

According to test status of fiber Bragg grating（FBG） sensor system applied to a concrete piles project, the anti-hitting performance of the sensor system is evaluated. Due to experiments, the flange joints and nearby regions are mostly prone to damage,the data connecting cables are also easy to breakage,while the FBG sensors are the most difficult to destroy. According to results of experiment, the corresponding protection measures are adopted. The glue-felt, plastic pipe and twine are used to protect the FBG sensor system, and the effect of the protection approach is approved by the experiment.
