| Abstract: | The technology of distributed fiber optic temperature measurement offers the possibility to monitor the leakage of embankment dams. This paper describes its principle and experimental results obtained by German experts. It is revealed that this technology can effectively perform leakage monitoring of embankment dams and has the advantage of distributed measurement with high accuracy and magnetic resistance. The installation of optic fiber has little interference to dam construction. This technology can also be used in the temperature monitoring of concrete dams. |
