摘　　要：提出将光子计数OTDR技术应用于施工设施的分布式动态测量,并对检测分辨率和灵敏度进行了理论分析。计算表明,在8km长度的光纤上实现10m空间分辨率,1kHz信号的检测是完全可行的。新型分布式动态监测技术有望成为检测对地下管线的侵扰和防范事故损害的有效方法。We have proposed that the photon counting OTDR technique could be applied to the distribution dy- namic measurement of construct facility, and carried on theory analysis in measuring resolution ratio and sensi- tivity. Calculations indicate that it is totally feasible to realize the space resolution ratio of 10m space on the optic fiber of 8km length, the measuring of 1kHz signal. The new type of distribution dynamic monitor technology is hopeful to become the effective method to take precautions against accident damage.
