Abstract: Houziyan concrete face rockfill dam (CFRD) is constructed in a narrow river valley which is not symmetrical. There will be large deformation in the dam after building. Reliable and stable monitoring system is critical for the dam. To establish an integrated monitoring system, Houziyan CFRD has not only summarized the successful experience of traditional monitoring techniques but also used some latest technologies such as fiber optical gyroscope, magnetic technology and distributed optical fiber temperature measurement system. This article elaborates three monitoring items, namely horizontal and vertical displacement, face slab deflection and leakage. And, the application principle of these technologies are analyzed as an example of reference to similar projects.
