Study on the Applicability of Optical Fiber Sensor for Road Slope Monitoring

摘要

Recently, optical fiber sensor is noticed as a countermeasure technology for road slope failures, and is possible to build them into a wide area monitoring system. We have jointed in " The cooperative research on the road slope monitoring by mean of optical fiber sensing technology", started by the Public Works Research Institute since 2000. In this paper, we reported the installation methods of optical fiber sensors on slopes and the results of the actual measurement. We found that the optical fiber sensors with the flexibility of installation are useful for the road slope monitoring.
