Experimental study on distributed optical fiber-based approach monitoring saturation line in levee engineering

摘要

Highlights?We designed a DTS-based experimental platform monitoring the saturation line in levee engineering.?The DTS-based monitoring experiment of saturation line in levee engineering is implemented on this platform.?We proposed a DTS-based approach monitoring the saturation line in levee engineering.AbstractSeepage is one of key factors which affect the levee engineering safety. The seepage danger without timely detection and rapid response may likely lead to severe accidents such as seepage failure, slope instability, and even levee break. More than 90 percent of levee break events are caused by the seepage. It is very important for seepage behavior identification to determine accurately saturation line in levee engineering. Furthermore, the location of saturation line has a major impact on slope stability in levee engineering. Considering the structure characteristics and service condition of levee engineering, the distributed optical fiber sensing technology is introduced to implement the real-time observati
