Abstract: Piping is an important failure mode of embankment dams. The lessons learned from historical failure cases clearly show that early detection of failure would be an effective measure to extend warning time for the people downstream. However, this is a difficult task. The present paper proposes an early warning system based on distributed strain and temperature sensing technology as a solution for new dam constructions or dam retrofitting. Therefore, the evaluation of the scope of application is needed. For this purpose, a parametric model by using the finite element method has been implemented. The theoretical basis and an analysis of the conventional monitoring systems are presented as well.
