光电技术在边坡稳定监测的应用

Application of Electro-optic Technology to the Slope Stability Monitoring

因边坡不稳定所造成的灾害损失巨大,这占全球尤其是我国国民经济损失较大部分。较之传统的监测技术,时域反射计(TDR)、光时域反射计(OTDR)、布里渊散射光时域反射(BOTDR)、光纤三维编织复合材料和光纤水听器等光电技术本身具有的高精度、高灵敏度、高增益充分体现了它在边坡稳定监测应用中的实时性、连续性、高效性和可行性,将成为边坡稳定监测研究与应用的新方向。

The disaster loss of slope instability is very huge, which takes a big part of the economic loss in the globe, especially in China. The high precision, high sensitivity and high gain characteristics of make the electro-optic technology, such as Time Domain Reflectomtry（TDR）, Optic Time Domain Reflectomtry （OTDR）, Brillouin Optic Time Domain Reflectomtry （BOTDR）, Optical Fiber Braided Composites and Fiber Optic Hydrophone, et al, more efficient, continuous, real time and high performance in the slope stability monitoring cpplications, compared with the traditional probing technologies. The electro-optic technologies are to become a new choice for slope stability monitoring.
