Through the application of distributed optical fiber sensing technology( BOTDR/A)based on Brillouin scattering,this paper made con-tinuous distribution roadbed structural health monitoring to Hegang-Dalian highway,near Dunhua ZT05 section,the monitoring results showed that the sensor in harsh construction conditions and climate,could survive,and could be accurately detected structure characteristics of highway.%通过应用基于布里渊散射的分布式光纤传感技术（ BOTDR／A），对鹤岗—大连高速公路，敦化附近ZT05标段的一部分进行了连续分布式路基结构健康监测，监测结果表明，传感器在严酷的施工条件和气候条件下，可以成功存活，并且可以准确监测高速公路的结构特征。
