| 中文摘要:开发一种自动化地质灾害滑坡光纤多参数监测系统，采用基于光纤光栅的反射中心波长随光纤光栅所受的应变或温度的改变产生移动，其波长移动量的多少直接反映应变或温度变化大小的工作原理。利用光纤光栅封装结构的变化，实现应变、应力、压力、温度、位移、振动等多种参量的测试；对多个光纤光栅的中心波长进行排布上的设计，则实现多点的准分布式测量，推动地质灾害监测技术的进步。 |

| Abstract:According to the shift of reflected central wavelength of fiber grating caused by the changing of strain or temperature, an automatic multi-parameter fiber monitoring system was developed for geological disaster monitoring, and the amount of wavelength shift directly reflect changing amount of the strain and the temperature. The monitoring on strain, stress, pressure, temperature, displacement and vibration was realized by the changing of fiber grating encapsulation style and dotty quasi-distributing measure was realized through the design of arrangement for multiple central wavelengths of fiber grating to improve the technology of geological disasters monitoring. |
