摘要
采用BOTDA分布式光纤传感技术监测上覆岩层变形的内部应力、应变、位移等参量,对指导生产具有重要的工程应用价值。试验获得BOTDA分布式光纤的测试数据,分析了Brillouin频移值随工作面开挖与上覆岩层破断变形的关系。
The internal stress, strain and displacement parameters of overlying strata deformation by BOTDA distributed optical fiber sensing technology have important engineering application value. The experimental data of BOTDA distributed fiber were obtained,the relationship between the Brillouin frequency shift and the fracture of the overlying strata is analyzed.
